Why hasn't anybody done this yet?

[PRcreator]

I'm planning on building up a minibike this summer, but i want to put a 4 stroke dirtbike engine in it, like a honda crf engine or something like that, something smooth and quiet.But the thing is that i have never seen anybody do it before, so i'm wondering if their is a reason for it? Like if it's difficult to do for some reason etc thanks

I don't know that it's never been done, but I would think those engines would have too much torque for a 6" wheeled mini. Those tires aren't meant to go faster than about 35mph, which is why you'll be hard pressed to find a 6" tire with DOT rating on it. I suppose it depends on what size engine you're talking about ? 125cc? 250?

I'll probably put a 125 or something around that range in there, 4 strokes don't have much torque at all and i'd get right wheels for it

Ill probably put some honda rukus tires on it or something

It's been done. My major question is why. A fella can go find a Honda Honda 50 and slap one of those lifans in it and have a much safer better riding bike without a big deal.

I have a CT70 with a 140 lifan in it. That thing is a monster, and cruises down the road comfortably.
