[. . . ] Aprilia was the first manufacturer in the world to believe in the potential of V twin engines in a market segment where nobody has ever had the courage to try. Impressive results in top level racing in 2005 and 2006 have shown that Aprilia was right. This exceptional engine (made entirely by Aprilia) has now been transferred to Aprilia production motorcycles. Totally reliable on the racetrack, the V2 engine has not been deprived of any of its technology or performance by homologation for road use. Engine development also proceeded hand in hand with chassis development from the word go, to ensure that these bikes handle and perform as totally integrated machines The 77° V angle between the cylinders is the result of innumerable tests aimed at maximising performance and minimising vibrations. The new engine vibrates far less than any single without even requiring a balancer shaft. The cylinders are integrated in the crankcase and are lined by replaceable wet sleeves. The intelligent design of the V2 has also permitted engine accessories to be arranged in an extremely rational way, keeping the powerplant as compact as possible. The results are amazing: Aprilia's V twin is one of the most compact in the world, smaller than many singles of similar displacement. Design solutions were specially selected for maximum power and a wide power band. Sophisticated electronic engine management, developed by Aprilia Racing, introduces a number of innovations for this type of motorcycle. The V2 engine sets new standards in this direction, and also guarantees beautifully easy access to all parts requiring regular service like plugs, oil filter and air filter. The engine sets a new record for a V twin, even with its starter motor fitted! [. . . ] And as always with Aprilia, good looks are just the outward shell of ingenious design solutions. The fixed air guides for example, allow the fuel tank to pivot upwards, giving easy access to the filter box. PRIMARY DRIVE The unrivalled technology and performance of the chassis are supported by a fantastic braking system. [. . . ]
