UPDATED March 2006 It's the closest thing you'll find to a genuine Grand Prix racing machine on the road, be it two wheels or four. Its 250cc two-stroke motor produces in excess of 60 brake horses, giving it a specific output of 240 bhp per litre - more than the fastest MotoGP bikes and on a par with competitive Formula One engines. And it's the last one - the fire-breathing two-stroke racer-roadster is about to become extinct. The next batch of Aprilia RS250 road bikes will be the last - as the last bike of its type, it's the last chance to own one new. Ever!!!!
