Blown engine in a Yamaha YZ 450 F MX bike, the owner then shoe-horned a CR 500 2 stroke engine in and with some specialized technical help, fuel injection added too!

Only 105 kg for this beast. Out of the gate about the same speed as a 450 MX bike, drop it a gear on the straights and it left them behind.

Might be thee way of the future?
