It will quite likely work, but if you look at the images you'll see that there appears to be no reduction gearing integral to it at all. It is almost certainly intended to be mated to a CVT in the power train. It is also just the engine only - no tank, or throttle control, or apparently exhaust system.

thats ok i have everything els laying around the garage, i got tons of extra exhaust and throttles laying around all i want to know really is if it will bolt on to a bmp kit?
 
A friction drive needs no reduction gear. If it has a centrifugal clutch of the right size it should work. The price is certainly good, but as noted above you will need to add a fuel tank, exhaust system, and throttle which will raise the cost a bit.
