Anyone know much about this little bike? Can you put a 125 cc dirt bike engine in them?

I don't believe you can. The frame seems a bit small for that.

But, sure, I am not.

Why yes you can. It can handle up to a 125 without much modifcations to the frame, but Tony Tice has been able to put a 250 engine in one, by extending the swing arm

Want to know how?


Currently I have a 80cc YZF motor in mine.

If you want more information otherwise on suping up this great novelty bike, check out http://www.teamcalamari.com/ as well.

Im on my 4th owned ysr.
