THE V2 ENGINE
The amazing V2 engine, and the more powerful 55.2 version, is the natural centrepiece of the RXV and SXV. Aprilia was the fi rst 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.

FIRST EVER
POWERED BY A SUPERB,
HIGH PERFORMANCE
Reduced displacement per cylinder has permitted use of an extremely compact and lightweight
V5.5
single-piece crankshaft. The engine responds instantly to throttle input, making the whole bike
faster and more agile.
Valve gear based on a single overhead cam and four titanium valves per cylinder gives the best
possible compromise between compactness, light weight and performance.
549cc V77° TWIN
Thanks to its advanced technology the V2 engine is extremely civilised and silent running. And
on an Aprilia, technology means reliability as well as performance.
V4.5
449cc V77° TWIN
The V2 engine sets new standards in this direction, and also guarantees beautifully easy access
to all parts requiring regular service like plugs, oil fi lter and air fi lter. The RXV and SXV also
boast far longer than average service intervals.
The same sort of effort has gone into weight reduction. The engine sets a new record for a V
twin, even with its starter motor fi tted! This has been achieved by an abundant use of super-
lightweight prestige materials. The central crankcase sections, for example, are made from
aluminium silicon alloy. All covers are in magnesium; the valves are in titanium; and the entire
gear train has been made lighter than ever before.
