It Wouldn't Work

The Busa engine is designed to power something that weighs about 200kg so there is the first problem.
Then you have : Major driveline issues - you aren't gunna have a chain/sprocket driven Datto
The list goes on and on.
Somethings are meant to be for bikes and some for cars.
It would work in an off road buggy though, I've seen similar conversions, but you basically just have a bike with four wheels.
