    Looks like that big pulley would fit the older 200x rear sprocket hubs, dont know how the front would work though. When mud gets jammed between the teeth wouldnt it just slip though?

    Nope, dont know anything about belts like that so I couldnt tell you. Biggest problem I see is finding a way to mount that on the front sprocket shaft.

    well the easiest would be to use one from another motorcycle. i am surprised no one here has done it yet. it would defintely have a cool factor

    Theres nothing wrong with chain drives, just alot of benifits with a belt drive, it wouldnt need serviced for a long long time, much cheaper to replace the belt, if it pops off it wont crack anything, wont snap or damage anything if it hits a rock. Basically it would be nice to have for higher hp machines that wear chains and sprockets out faster.

    what is so hard about using a setup from another bike? who is doing all the billet peices for everyone on this site? the front sprocket would probably be the easiest to machine. what about the benefits for those guys running in the dunes?

    There's been countless problems with belts slipping on primaries plus do you have any idea how fast a belt will snap when a stone gets lodged in a pulley? This will work fine for armchair racing and pit riding but I wouldn't try anything too serious with it.

    I've seen $2000 bobcat tracks snap from trying to pass stones, I'm 100% positive that you could snap a drive belt.
