Safety of the 212cc motorbike kits?
How safe are those 212cc kits that you can mount on a bike? I a have been thinking about getting a cheapie mountain bike with rear suspension. Brace the hell out of it, then go put dirt bike parts on it.... (Triple tree, real breaks, rims, tires, etc, etc) I don't see me being able to get a hawk (or any bike) anytime soon. (As in the next year) So if anyone can state how well those things can hold up with time, or has anyone made one of these kits?
Sincerely, John Doe

The only reason to build one of these is for the fun of it. You dont really save any money. Ive got well over $2000 into my 200cc bike. Its fun but I would have been better off with a china bike.

i know that people around here ride the smaller cc bikes and are always replacing rear rims because the drive sprocket runs off of the spokes that were never made to have torque on them ... if i were going to build one i would mount the engine over the rear tire and make/buy a unit that drives off of the rear tire, not the spokes

Friction drive with a 212cc is not a good idea. It will make your tire bald very quick and when it gets wet it slips. You want to drive it with a jack shaft and a strong sprocket.

sprocket is not the problem, it is what the sprocket goes on

The sprocket goes on a disk brake hub. Use a sprocket instead of or with the disk. My setup uses a adapter I made to use with a disk and a one way sprocket so the pedals dont spin when your riding. One side of the hub you peddle with. The other drives the wheel.

I've ridden a few mainly the 66cc marketed as 80cc but a few bigger. Unless you do some serious stuff to them like Merlin has they are supper sketchy scary. The tires / rims and brakes seem to make the most difference but having a good suspension and drive train would be a big plus. I knew one nut who put one on a fixed gear. It did not last long.
