RSV4 Factory AF1 Racing Dyno Test Leo Vince Slip-On

This is the new 2010 Aprilia RSV4 Factory. The new RSV4 weighs a true 434lbs on our certified Intercomp scales with about a gallon of fuel and every other fluid needed to ride, a VERY light bike for out of the crate. This one lost about 10 lbs with the stock pipe being replaced by the Leo Vince Slip-On. Factory Pro Dyno's at this bhp level read about 17% lower than the average Dynojet dyno putting to rest hopefully the "underpowered" rumor circulating the internet, a stock 2009 Suzuki Huyabusa makes 145 on this same dyno. The DynoJet correction factor would be about 163 DJHP. The pipe on this bike is the latest offering from Leo Vince and is running a completely stock mapping in the ECU as well as closed loop feedback from the o2 sensor, something I will fix soon. There is another 10-12 "easy" bhp in this machine and as much as 20 more if you are a "balls out" guy with deep pockets, putting it in the same league as Ducati's Desmosedici or D16RR for 1/3 or less the price. The sound from the 65 degree Aprilia/Piaggio engine is music, like only Italians can make come from an air pump.
