The two wheel drive "sport" (aka racing) Yamaha has some really great components on the front end!!! As hard as they are ridden I would imagine they wreck a few of them.... Got a motorcycle junk yard down there to check out???

The larger 600 and 700 cc Kawasaki's and Yamaha's are mostly all 4wd stuff. One I looked at would require nothing more then removing the half shafts and a U-Joint yoke to make it a 2 wd.---think that was a Yamaha Grizzly maybe???

Even the plain Jane quads have a lot of front end travel, some of the race quads look like they have about 7 or 8 inches of travel and are heavy duty enough to take some really serious pounding in the dirt!!!!
