All ATV rear sprockets match originals in design (solid-mount/bolt-on and rubber-damper type) unless noted otherwise
At this time we are not able to specify on our website the standard tooth sizes of the sprockets or size and length of chain for your motorcycle. We will display every sprocket that fits. If you need the standard tooth size information or chain size and length, call us toll-free 800-969-7504
I purchaced this sprocket to replace my worn stock one on my 07 400ex to run out the factory chain. I put it on and the retainer would not line up right with the splines on the output shaft. The threaded holes are machined wrong so that the retainer will not bolt on and hold the sprocket in place. So i cald Dennis Kirk told them the problem and they sent me out a Moose sprocket put it on the next day and all is well.
