As far i know, my friends Aprilia RSW250GP it's about 92hp in her best setup ( 5 times european champion with this bike ), and factory ones were over 100 ( that's in 2005 ), i suppose that the last factory ones were over 105 ( the best ones ). Of course, my friend's bike it's not "standar" spec, but it's far away from the factory ones. He was wilcard at some races and the factory bikes were easy 20 km/h faster, not to mention the tyres ...

Before the Apri, he has a TZ250 ( ex D'Antin team ) before that he had a TSR, and the first 250 he had was a 1998 RS250, if my memory dont fail, TZ was about 85hp ( year 2000 ), and i dont remember anything about the TSR and RS, but i can ask if somebody wants.

120hp in a 250 .... with Turbo ??
