2014 Performance Aprilia Caponord 1200 – First Ride

Sardinia, Italy—When I first saw the Caponord at the EICMA show, I quickly dismissed it as a smart, full-dress evolution of the Aprilia Dorsoduro, a bike conceived to snatch a slice of the growing adventure-touring pie from the iconic BMW R1200GS. However, after riding the Aprilia Caponord 1200 on some secluded and twisty roads on Sardinia, I must apologize to the Aprilia technical team: The new Caponord is actually a smartly conceived and very efficient street-biased adventure-tourer that only looks inspired by the Dorsoduro when seen from afar.
In reality, it’s a completely new bike. The test ride, on roads soaked by a strong storm, underscored the efficiency of the Caponord, which has the most advanced electronic suite ever installed on a bike, aiding rider safety, comfort and pleasure. The following is a list of the electronic systems on the bike, which reveals the company’s leadership in this domain:
RBW: The ride-by-wire electronic throttle control has three selectable responses—Touring, Sport, Rain.

ABS: A double-channel system from Continental individually manages the latest Brembo radial-mount, monoblock calipers and twin 320mm front disc brakes, plus the floating single-piston rear with 240mm rotor. The ABS is integrated with the ATC system, but can be switched off independently.
ATC: Aprilia Traction Control, likely the most advanced and effective today, has three settings: Level 1, for a pure sport-riding experience; Level 2, for everyday use in the city and in touring; and Level 3, for enhanced safety on low-grip surfaces. ATC can be switched off, and is capable of self-calibrating when fundamental components of the rolling gear, such as tires, are changed.
ACC: Aprilia Cruise Control is part of the Travel Pack, the grand touring Caponord.
ADD: Aprilia Dynamic Damping goes well beyond the ESA-type adjustable suspensions operated via a handlebar-mounted switch. The Sachs suspension units, front fork and cantilevered rear shock, have damping managed by a dedicated ECU with proprietary Aprilia software and related actuators. They essentially “read” the riding conditions and riding style via specific sensors. Skyhook, from the automotive world, handles the low-frequency loads, whereas an acceleration-driven system handles the high-frequency loads. Together, the two systems ensure higher comfort and superior dynamic performance. Since neither can modify the spring load, they are considered semi-active, not fully active. The rear shock absorber, however, can modify its spring preload based on signals coming from a sensor monitoring the angle of the swingarm in relation to a fixed point on the frame. This active system resets the correct angle by preloading the shock absorber spring, via a step motor, on the basis of four pre-set mappings (rider only, rider with passenger, rider with panniers, rider and passenger with panniers).
Stepping away from the electronics and into the world of internal combustion, the Aprilia 1200 90-degree V-Twin has been retuned to 125 hp at 8250 rpm RPM, which is down a bit from the Dorsoduro’s 130 hp at 8700 rpm, but has a broader torque curve. Peak torque now is 84.4 ft.-lb. at 6800 rpm, instead of the Dorsoduro’s 84.9 at 7200 rpm. The engine has undergone extensive modifications, beginning with 52mm throttle bodies in place of the 57mm units of the Dorsoduro engine. To improve flexibility and smoothness of response, two injectors are fitted to each throttle body, and an oxygen sensor is included downstream in each exhaust port for a perfect calibration of the injection as well as reduced fuel consumption and lower exhaust emissions. A 690-watt alternator supports all the complex electronics and the rest of the electrical components, including the new and more powerful lighting system and the optional heated grips.

Fluo Red -or- Matte White The Dorsoduro is sort of just a Super-Motard version of the Shiver. So it’s basically a Shiver with longer, softer suspension and more of a dirt bike riding position. Like the Shiver but want something edgier? The Dorsoduro is sort of just a Super-Motard version of the Shiver. So it’s basically a Shiver with longer, softer suspension and more of a dirt bike riding position. I don’t know why but when I get on a Dorsoduro, I immediately feel like I want to do something illegal, like go down those steps or ride over that Volkswagon. But seriously, it’s definitely a bike to give you a thrill immediately out of the garage.
Call it your urban assault vehicle. Yet it can be ridden long distance. A couple years ago one of our customers rode his to Montery, California and back. Like the Shiver, the Dorsoduro’s V-twin engine produces a strong, wide, & flexible powerband. And it’s no slouch with 92 peak horsepower at the crank. It’s got a slightly lower peak than the Shiver but more low-end response, plus it’s geared a bit lower.

Both bikes are very responsive due to their ride-by-wire fuel injection system. This means that when you turn the throttle, you’re giving an input to the computer, which makes decisions based on your twist. Conventional fuel injection merely opens the throttle(s), leaving various sensors to react. Naturally then, ride-by-wire is more responsive. Too fancy? It does have an airplane-inspired redundant backup system. And it’s been very reliable. What if you don’t want more responsive? You get to choose 3 levels (called rain, tour, & sport) at the push of a button. Sport is a bit jumpy in stop & go traffic, so most choose tour around town. And we once had a fellow do a test ride a week after getting his motorcycle endorsement, having never owned a bike; he chose rain mode. Ride-by-wire also means less maintenance: you never have to synchronize the throttle bodies (OK, you really can’t manually at all!).

And speaking of maintenance, this is no Italian nightmare. It’s water cooled and the dual overhead cams per cylinder are driven by chains with self-adjusting tensioners. There are no fragile belts that require frequent replacement and manual adjustment. The valves are supposed to be checked for adjustment every 12,000 miles, but this hardly seems necessary, as we’ve never seen a valve out of adjustment on an Aprilia 750 engine. Heck, the oil & filter are only supposed to be renewed every 12,000 miles in normal use; we’d suggest more often with lots of short trips around town in our cool climate. The filter’s cheap & easy to access, as are the fill & drain plugs, and there’s a sight window for oil level.

 The Dorsoduro comes with a sealed battery for long life and a 450-watt charging system capable of powering electronic accessories, such as hot grips. We also carry the full line of Powerlet products to add power ports for anything from cell phones to GPS and heated gear. Other popular accessories include passenger hand rails, soft saddlebags, luggage rack, and even a hard trunk. The factory warranty is two years with unlimited miles. And the Dorsoduro has been very reliable model. Brakes and suspension are “sporty standard” as opposed to a harder-edged “sport naked” like the Tuono V4. And the Dorsoduro has some deluxe appointments, such as radially-mounted 4-piston dual front disc brakes, adjustable single-shock rear suspension, upside-down adjustable front forks, adjustable hand levers, hydraulic clutch, and stainless steel brake hoses.

The original US Dorsoduro in 2009 was a 750. In 2011 we got a 1200 that certainly had more power but kind of lost the good feel of balance between power and weight. For 2014 we got just the 750 back, this time with ABS brakes added, but the price stays the same as it was for the non-ABS 750. The 1200 engine is still used in the European big Dorsoduro and we’ll see it back in the new Capo Nord adventure touring bike.

Review Aprilia Tuono V4R APRC

The Tuono V4 R maintains a transparent parentage with the twice SBK world champion within the proportions of the tail fairing, saddle, tank and aspect panels, and is one in all the most effective samples of Italian bike style from the past decade for its excellent balance between formal beauty and performance.

The rider are going to be taming this beast from a riding position tailored to make a symbiotic relationship between the body and therefore the bike, for unparalleled feedback through the 3 points of contact - the saddle, footpegs and handlebars. On the Tuono V4 R. however, the rider sits with less weight taken up by the arms, creating the bike less strenuous to ride and very nimble and controllable on the road.

The original style of the saddle, that is generously sized and specifically formed to comfortably accommodate a passenger, blends perfectly with the fashion of the aspect fairings and tail fairing.

From the vantage purpose of the saddle and with the broad tapered handlebars firmly in your grip, you immediately discover that the

APRC (Aprilia Performance Ride Control) version options an immediately intuitive joystick for rapidly accessing and adjusting the functions of the second generation electronic dynamic management suite developed by Aprilia to let the rider explore the physical limits of riding.

Review Aprilia RSV 4R APRC

We reside times for motorbike technology, terribly special. On the one hand we tend to live rescue of little displacements, engineered on the bikes simple and basic techniques known and tested, generally to the limit of recycling, whereas at the opposite extreme we discover technologies that evolve at the speed of sunshine in search of ever bigger performance.
And ‘there, within the section of the race reproduction that return the foremost vital new techniques, borrowed from the planet of racing and coming back, year when year, the bikes that we will purchase within the dealership.

Aprilia, that has continuously stood for innovative capability and its technical experience, introduces vital new supercar on its prime in 2011.

The RSV4 R, we tend to tried on the track at Estoril currently takes the name APRC that represents a big technical distinction compared to the 2010 version, because it implies that even the “basic” model the package is put in Aprilia Performance Riding management. The RSV4 R 2011 conjointly brings with it the opposite enhancements introduced since the RSV4 Factory APRC and then extended to V4 Tuono R.
Changes accordingly, the value rising to selling € eighteen,000, whereas the remainder of the budget, together with color with black competition as against white glam, remains unchanged.

As anticipated, the Aprilia has introduced the electronic package APRC at the top of 2010 when it launched the RSV four Factory Special Edition version of the already developed RSV four Factory performance.
The electronics package APRC (Aprilia Performance Ride Control) is, at present, the foremost advanced management system, dynamic driving on the market on the market.

It essentially consists of 4 sub-systems that operate in an exceedingly coordinated and synergistic: ATC, AWC, ALC and AQS using the signals received from an inertial platform, with 2 accelerometers and 2 girometri that enable the unit to reconstruct the dynamic conditions of motion and respond accordingly to the engine management. The pilot will modify freely and independently of every system element APRC.

The system is clearly the foremost vital dell’APRC ATC Aprilia Traction management. this is often an innovative traction management system, developed with patented Aprilia, that has as main goal to assist the pilot to enhance his lap time. due to the utilization of the inertial platform and ride-by-wire, ATC operates on the management of torque from the engine in line with many steps, and permits the rider to manage the drift out of corners, increasing its sensitivity on the throttle, reckoning on the angle of inclination of the bike.
Traction management is adjustable on eight levels, just by pressing the joystick on the left handlebar to regulate the amount of traction management to the track conditions, tires or asphalt.

Aprilia RSV 1000 Mille SP

The 'SP' stands for Sports Production, and the Mille SP is little more than a race bike for the road. Despite looking almost identical to the RSV Mille, nearly every part is different. The engine has a different bore and stroke, giving a smaller 996cc capacity, to allow higher revs, and there is only one spark plug per cylinder to allow bigger valves. The frame is unique to the SP, with adjustable engine position, steering head angle and swingarm pivot, and 20 per cent stiffer.

The fairing is made of lightweight carbon-fibre, and the Öhlins suspension is fully adjustable. The SP was built as a 'homologation' machine, to allow the firm to race in the World Superbike championship. It was a limited-edition bike, with only 150 produced.

Aprilia RSV 1000 Mille R

Competition may come and go, but the Aprilia RSV 1000 R remains the unquestioned top dog among supersport motorcycles for its amazing handling on road and racetrack. The Aprilia RSV 1000 R has shown its competitive edge in world endurance racing, where it is the only production twin able to compete on even terms with the best four cylinder machines in the world, as demonstrated by the excellent results achieved. Legendary races like the Le Mans 24 hours and the massacring Bol d’Or 24 hours have shown exactly how effective the twin cylinder Aprilia RSV 1000 R is on the racetrack , and how totally reliable it is too.



Endurance racing has provided more than just an unforgettable experience. It has served as a valuable test bench for the latest technical solutions now appearing on Aprilia production bikes.



The Aprilia RSV 1000 R is determined to maintain its supremacy as the best sports twin money can buy, for its advanced technology and for its amazing performance.



But what counts the most is the fact that the Aprilia RSV 1000 R is still the bike to beat when it comes to ease of riding. Because riders feel so instantly confident on an Aprilia RSV 1000 R, they really can ride at the limits of their abilities and stay totally relaxed too.



The benefits are obvious in terms of less physical and mental stress, faster and safer motorcycling and the ability to remain fully concentrated for far longer, factors that contribute to success on the racetrack and safety on the road.



The main characteristics of the RSV 1000 R:

· Öhlins Racing fork with TiN (Titanium Nitride) coated stanchions and radial caliper mountings;

· The latest generation V60 Magnesium engine with Ø 33 mm exhaust valves;

· Larger diameter exhaust headers;

· External catalytic converters, installed nearer to the header pipes for improved efficiency and respect for the environment;

· Euro 3 homologation.

Constant technical development has enabled Aprilia’s engineers to carry on improving the performance of the motorcycle that already represented the state of the art for twin cylinder supersport machines. In this latest RSV 1000 R, the V60 Magnesium engine is not only cleaner but even more powerful, confirming its reputation as the world’s mightiest production twin. The modifications needed to achieve homologation to strict Euro 3 standards have not stopped Aprilia squeezing another 4 horsepower out of this amazing engine. The latest powerplant delivers 105.24 kW (143 HP) at the crank to push the bike to a top speed of over 280 km/h, aided by improved aerodynamics and even more efficient engine breathing.



Even the chassis has been updated using the experience gained from a year of international racing that has seen the RSV defeat all rivals on the world’s stock racing circuits.



This unbeatable engine and chassis go hand in hand with top-quality components, and an even higher level of prestige equipment, placing the Aprilia RSV 1000 R in a class of its own not only in performance but in quality to price ratio too.



V60 MAGNESIUM ENGINE

The 1000 cc V60 Magnesium engine has long been the standard setter for production twins, but constant evolution and development at Aprilia’s R&D department have now made it even better.

33 mm exhaust valves and new, larger diameter exhaust headers have been fitted to improve engine breathing. In this form the V60 Magnesium now puts out even more power, topping 143 HP at 10,000 rpm without losing any of its legendary usability and proverbial Aprilia reliability.



The new satin finish silencers have catalytic converters installed nearer to the collector pipes. This solution has reduced converter activation time by 50% while further reducing the level of exhaust emissions. The Aprilia RSV 1000 R conforms easily to the strict limits required for Euro 3 homologation. The second section of exhaust has also been extended by 200 mm to boost torque at low revs.



Optimised fluid dynamics inside the cylinder heads has been enhanced by improved mapping of the combined ignition and fuel injection systems to achieve higher power throughout the useful rev range.

The V60 Magnesium breathes through the ‘Air Runner’ dynamic air scoop located in the middle of the nose fairing. This has been redesigned to increase air flow to the engine’s ‘lungs’. The Air Runner scoop is located precisely where dynamic pressure is highest, exactly along the bike’s centreline.



From the scoop, an air duct passes through the steering head to take ram air to the generous 10.3 litre airbox.



A choke valve inside the duct, controlled by the engine ECU, regulates flow to provide the engine with air at exactly the right volume and pressure. The engine therefore packs incredible punch right through its extended speed range, enabling the rev limiter to be set at 11,000 rpm.



The mighty roar of the V60 Magnesium is muffled by two differential volume Helmotz resonators to reduce intake noise at the most critical engine speeds.



The airbox also houses an idling motor. This operates an electronically controlled valve that deviates air downstream of the butterfly valve to make it easier to start the engine from cold and to stabilise engine idling.



The Air Runner also performs a structural function. It incorporates two lightweight aluminium arms to hold the cockpit fairing and headlight so that there is no need for ugly brackets.



A new panel type air filter reduces pressure drop and improves engine efficiency.



The engine’s fuel injection system features 57 mm throttle bodies and one injector per cylinder.

Thank to the Air Runner ram air scoop, pressure in the airbox increases as the bike accelerates, leading to a 3% gain in power at maximum speed.



A new generation engine management unit, made in conjunction with Siemens VDO, controls all engine parameters. The ECU receives real time signals from 15 parameter sensors and processes these to control the actuators in real time too. (Parameters include air and coolant temperature; atmospheric, airbox and oil pressure; Lambda sensor oxygen level; crankshaft, camshaft, and rear wheel speed; throttle position, side stand, clutch and neutral position; and battery voltage.)



The flash EPROM already contains racing mapping for unrestricted exhausts. Aprilia service engineers can easily change mapping on request from customers who intend to use their bikes exclusively on the racetrack.



All engine data passes through a CAN (Controlled Area Network) line to the instrument panel, which also acts as a diagnostic terminal. In the unlikely event of a malfunction, it is a simple job for service engineers to identify problems. The CAN line uses only two wires to transmit all data. This simplifies the electrical system enormously as well as reducing the total weight of the bike.



The RSV 1000 R also has a close ratio gearbox, to make it easier to make full use of the amazing power of the V60 Magnesium engine.



Despite so much technical evolution, the characteristics that made the original RSV stand out are still there.



- Longitudinal 60° V twin engine with 4 valves per cylinder and double overhead camshaft, driven by a mixed chain and gear system.

- Electronic fuel injection with 57 mm throttle bodies, one injector per cylinder, and an ‘Air Runner’ ram air scoop.

- CDI ignition with one plug per cylinder. Ignition is controlled by the same integrated engine management system that also controls fuel injection.

- Dry sump lubrication with double trochoid pump, separate oil tank and oil cooler.

- Mixed gear/chain valve timing drive with the two gears (one per timing chain) located in the crankcase to reduce cylinder head dimensions.



The RSV 1000 R’s sophisticated twin cylinder engine also incorporates the following exclusive Aprilia patents:

- AVDC (Anti Vibration Double Countershaft).

- Hydraulic action clutch with radial master cylinder assisted by the patented PPC (Pneumatic Power Clutch) system to control rear wheel bounce during fierce braking.



FRAME

Years of racing at the highest levels have allowed Aprilia’s R&D section to design a frame that is acknowledged as the best production bike frame around.



One of Aprilia’s fixed objectives when designing the RSV 1000 R frame was to achieve perfectly centralised mass. In line with Aprilia practice, the frame incorporates aluminium-silicon castings and Peraluman 450 pressings. The frame has been optimised by extensive finite element analysis and boasts excellent torsional rigidity though it weighs only 9,650 grams, a figure matched only by specialist racing frames.



Aprilia’s obsessive search for perfection, plus the experience gained from production bike racing has nevertheless led to small but important improvements to what was already the best frame on any machine of this type. The steering head’s rake angle has increased from 24° 45’ to 25° to give a slightly longer trail. Stability is better as a result, so that the new RSV 1000 R inspires even more confidence than before, without losing out on its acclaimed agility.



The new RSV 1000 R swingarm is made from extruded Peraluman and Al Si7 castings. Its double arch design provides a clear passage for the new twin silencer exhaust system.



Here too, cross-sections and wall thicknesses have been optimised using finite element analysis. The RSV 1000 R swingarm weighs only 4,860 grams, well under the swingarm weight benchmark of 5 kg.



SUSPENSION

The fantastic Öhlins Racing fork fitted as standard to the RSV 1000 R represents the state-of-the-art for this most important of all components in determining how a motorcycle handles. The new fork has 43 mm stanchions with titanium nitride coating for a friction-free sliding action. Its advanced design with longer sleeves and shorter fork bottoms reduces load at two critical points, the slide bush and the stanchion to fork bottom joint). Wheel travel is 120 mm.



Like all top racing forks, the Öhlins allows precision adjustment of compression and rebound damping as well as spring preload.



The Sachs rear monoshock incorporates a separate piggy back nitrogen cylinder and is also adjustable in preload, compression and rebound. A characteristic unique to Aprilia is that the length of the monoshock can be adjusted directly from the unit itself so that the rear end of the bike can be raised or lowered to achieve whatever setup may be required and to match rider preferences and other suspension adjustments.

BRAKES

Top supersports demand top quality brakes. The RSV 1000 R is again at the cutting edge of technology, and is equipped with Triple Bridge, radial caliper front brakes developed by Aprilia in conjunction with Brembo. The 320 mm floating steel discs on the front wheel feature narrower braking bands for reduced wheel weight and inertia and therefore more agile handling.



The RSV 1000 R’s radial calipers are combined with a radial master cylinder to form the most sophisticated braking system fitted to any current production bike.



The front and rear braking circuits both use aeronautical metal braid hoses to eliminate the pressure variations associated with conventional rubber brake lines, guaranteeing maximum braking precision.



COMPONENTS

What places the Aprilia RSV 1000 R in a class of its own is the care taken in its design and manufacture and the attention paid to every single component on the bike. The result is increased performance and functionality, with reduced weight and a quality of finish that no other bike can equal.





The following components deserve a special mention:

- Öhlins Racing fork with titanium nitride (TiN) coated stanchions.

- Aluminium steering pin and bottom yoke.

- Brembo Triple Bridge radial front brake calipers.

- Forged caliper mounting blocks for greater rigidity and stability under braking.

- The combined digital and analog instrument panel receives data on all engine control parameters over a CAN line and incorporates memory to allow it to act as an integral part of the self-diagnostics system. The instrument panel provides the same readouts as the previous model (including a self timer with a 40 lap memory), but is now extremely modern and compact in design and weighs only 220 grams. All functions are controlled by three conveniently located keys. The LED backlighting may be set to three levels and is white for the analog instruments and red for the digital display.

- The headlight cluster incorporates four lights for perfect night riding vision. The great care taken over the design and finish of the RSV 1000 R also transpires from little but important details like bulb holders made from blue anodised aluminium.

- The white lens direction indicators are fully integrated in the bike’s body. The front indicators are moulded into the rear view mirrors while the rear indicators are built into the tail. This means that there is no need to remove them for track use. The rear number plate holder can also be removed quickly and easily to comply with competition regulations.

- Even the ignition key is specially made for the RSV 1000 R and carries an internal identification code. The ignition block has an immobiliser fitted as standard.

- The alloy wheels share the same forked spoke design as the exclusive forged wheels of the RSV 1000 R Factory

Aprilia RS 250 Chesterfield Replica

YOU DON'T need to be Max Biaggi to get your socks blown off by the new RS250. But you do need to be to find much wrong with it. At the world launch of the stunning 250 at Misano the RS seemed to have it all: a fast motor; an exquisite chassis and, perhaps more than anything, the looks and detailing worth flogging granny for. All it lacked was the presence of the newly-crowned 250 world champion himself to give the bike his the Noale marque's lengthy experipersonal seal of approval. ence of strokers, through everything

We've been waiting a long time from 50cc super shoppers to whizzo for Aprilia's 250 screamer. Despite 125s and world championship 250 trials and GP competition bikes, the eagerly-expected 250 road bike seemed to be the firm's Achilles heel. Over the last few years reports of 250 prototypes seizing or proving otherwise unreliable repeatedly found their way back to the UK. And for a variety of reasons Aprilia struggled to make a reliable V-twin stroker competitive with the class-leading RGV Suzuki. Ultimately, Aprilia gave up, instead surprisingly turning to Suzuki itself three years ago to forge a deal whereby the Japanese manufacturer now supplies a version of the proven RGV engine, redesigned to Aprilia's spec, to power the RS.

However ironic, it's certainly an effective move. Although the engine remains essentially RGV, top end, exhaust, ignition, cooling and overall gearing changes make the engine in the RS both noticeably different in character and more potent on the road or track. And, gearing aside, the track (or maybe a glass display case) is where it belongs.

Below 8000rpm you'd be better off on a bike with less than half the power: the RS kickstarts reluctantly, idles splutteringly and then burbles asthmatically until the revs approach five figures. That's the price you pay for the all-singing, all-dancing fireworks at the top of the range. But cog down or patiently wind the tacho needle over nine and the twin pipes crispen and the bike canters forward, faster and faster like a true racetrack refugee. It's all over, suddenly, at 12 thou — then you notch up a gear for more: bouncing like a screaming maniac between ten and ll,50()rpm; keeping one eye on the tacho, your foot on the gear lever and your heart in your mouth. It's completely addictive, hooliganistically noisy and, Aprilia claims, a smidgen faster everywhere than the RGV.

Its only problems on the track were gear ratios that are slightly too wide, especially in the lower gears, to always keep within the edges of that powerband. Although the gearbox itself is identical to the RGV's, a one tooth smaller rear sprocket raises overall gearing but also has the effect of spacing the ratios a touch wider. But on the road it's unlikely to make any odds.

Where the RS really comes into its own is on the brakes and into corners. Here the RS makes all previous racer-rep stroker 250s seem five years out of date. And it does so with style. The Aprilia may carry a premium price tag but it's the no-expense-spared approach the firm has taken to the bike's chassis and cycle parts that will make the outlay worth it.

The riding position is classic racer crouch but, as is Aprilia's way with 125s too, roomier than you might

Aprilia's 'RGV

DON'T BE FOOLED by the 'Aprilia Racing' on the cases. The RS engine is built entirely by Suzuki and, bar a handful of crucial Aprilia design changes, is mechanically identical to the RGV250. (Quite why Suzuki cooperated with Aprilia to build a direct competitor to its RGV remains a mystery. Aprilia says Suzuki didn't consider the RS a rival and RGV sales are now so low Suzuki says its future is in different types of bike.)

Barrels, crank, clutch and gearbox are all identical to the RGV, however new heads featuring reshaped combustion chambers (which hike compression to a whopping 13.2:1 over the RGV's 7.3:1), enlarged coolant channels, all-new expansion chambers and a reprogrammed ignition 'black box' make the RS engine a markedly more potent beast.

Aprilia is claiming a peak of 69bhp for the RS - eight bhp over the RGV -plus a power curve supposedly better throughout the entire range.

Gearbox and clutch are also stock RGV but the Aprilia wears a slightly smaller rear sprocket which has the effect of raising overall gearing (even on the test track's long straight the RS was still short of the redline in top but showing 200kph, or 125mph, on the speedo) and exaggerating the spacing between the ratios.

Fears about longevity should be quelled by the news that in Italy the bike is being offered with a three year warranty. The UK is expected to follow suit. On the launch, 15 bikes were caned mercilessly all day long without a single seizure expect. The bars are quite flat and widely spaced and, though the pegs are so high they're impossible to ground even on the track, the seat is such that it's not too cramped. The RGV seems much more compact but in truth it s the little Aprilia that is shorter, lighter and lower.

Once aboard you're instantly at home. The RS's light and low down weight allied to steering that is slightly slower than the RGV make the machine extremely predictable and easy to get on with. And it just gets better the faster you go.

The brakes are absolutely astonishing, with the power to loft the rear wheel with just two fingers and the sensitivity to confidently trail deep into corners. But overall it's the balance between the super-rigid frame and top-quality, multi-adjustable suspension that impresses most. Though a couple of kilos lighter than the RGV, the sensuous pressed aluminium frame gives the RS a solidity and integrity the RGV somehow lacks. The inverted Marzocchis up front inspire complete confidence as does the rising rate rear shock once the compression damping is wound right off (via a convenient knurled knob poking from the side panel) — even if the super-grippy Pirelli Dragon rear tyre did cut up alarmingly during the session. Put that lot together and you've got one of the best-handling and least daunting road bikes ever built.

All of which would be fine for a special or the sort of bike destined only for proddie racers but the telling class of the RS250 is not only what it does but how well it's been put together. The styling speaks for itself. From whatever angle you view it, the RS250 is mouth-wateringly beautiful. But when you go through its component parts, one by one, it gets better yet: the alluringly-sculpted front mudguard; the perfectly-blended headlight; the slim and smooth (but useful) mirrors; that fantastic pressed and welded sheet aluminium frame and 'banana' swing-arm; the neatly machined footrest hangers and the lovely forged and polished aluminium heel protector plates. Not to mention the svelte seat unit complete with closely-fitting pillion cover under which lives the two-stroke filler and a useful sandwich compartment.

It's these things, the attention to detail, the flourishes of design and the quality finish (a few peely stickers apart) that really ensures the RS250 will blow the RGV into a cocked hat. Neat welding, polished aluminium and (admittedly fake) carbon fibre abounds. Plus of course, there's the unique (and gimmicky) LCD lap-timer which doubles as the temp gauge in the console. Phew, there's so much to the RS, so much style, flair and potential pub boasting to it that, in a way, how the bike goes is almost irrelevant. At a predicted £5495 _{the 200 bikes earmarked for the}

UK will probably be lapped up on looks alone. But, having ridden it, the RS turns out to be faster (just), handles better, is better braked and, for my money, is much more fun than the RGV too. If any bike is going to come close to the Ducati 916 for sheer desirability this year, the RS250 is surely it. And against the 916s £11,000 price tag, the little Aprilia is an absolute steal.
