  • Great little engine for a Honda XR250R.
I mounted this engine onto a 2002 Honda XR 250 R. With some slight modification to the motorcycle frame this engine fits well for that application. Once I hooked everything up, the air engine started right up and seems to be very reliable.

  • Vertical only, big motor
I liked that it came as advertised and un damaged unfortunately it’s insanely big I was trying to fit this on my grom but it’s angle is going to require custom motor mounts also just a heads up this motor does not want to be at an angle what’s so ever I’m pretty sure it’s from the xpro 250 storm dlx so it’s meant to sit like a dirt bike ... show more
