Aprilia is doing final longevity testing on their new 1.0L V4 motorcycle engine which can produce 220 horsepower. This power level will beat out every other production street bike on earth in HP. The development of this engine came from the street level interest in the MotoGP racing. Most bikes run a V4 engine and it doesn’t take long for enthusiasts to want something close to mess with. It will be very interesting to see what the modifiers will be able to do with this platform. Oh the engine swap goodness.
