What s the heaviest car you could swap a motobike engine into? ive seen caterhams and west fields and the occationall mini, weighing 500Kg and 700Kg repectfully, has anyone ever heard or done one on a car weighing 800Kg-1000Kg

As heavy as you like, it's just sorting the drivetrain that's the issue, nothing with the engine itself.

FWIW I've seen Yamaha and Kawa motors in 1200-1400 4wd cars.

So basically, it's just the gearbox that's the weak point? Ok, thank you
