RS 50

£2,399.00

You might think that you can only find lightweight wheels, radial callipers, an aluminium frame and swingarm, and an under-seat exhaust on a big bike. But you would be wrong. Because these are the specifications of the Aprilia RS 50, the undisputed top dog in the world of 50 cc supersport motorcycles. The Aprilia RS 50 is a genuine sports motorcycle, and comes packed with the sort of technology normally found only on a GP racer. 

Its eye-catching, racing lines and determined, aggressive shape tell you that the Aprilia RS 50 knows no compromises. This 50 cc supersport is made to thrill and has all the performance needed to do so. 

In terms of style, the flagship of the Aprilia family, the RSV 1000 R - the twin that beat Japanese four cylinder racers to win the 2006 Master Bike trophy, clearly and unashamedly, inspires the RS 50. This same thirst for victory is found in the RS 50, together with technology developed for the world-beating Aprilia 125 GP. No wonder the RS 50 is the machine that all other 50 cc bikes have to beat. 

The specifications for the 2007 RS 50 are simply breath-taking. The following are just the most important:
Aluminium frame
Aluminium swingarm
Lightweight wheels with ‘Y’ spokes
Radial calliper front brake
Euro 2, two-stroke engine
Fairing based on that of the RSV 1000 R
Analogue/digital instruments
