This clutch hub was a little better than the one I replaced. The hub coming off was an aftermarket almost identical to this one. The hub coming off the bike was split at the keyway, so I dont see any improvements in that area to keep it from splitting as they claim. The only reason I say it is a little better is because the threaded studs that come out of the hub are fully welded instead of the two spot weld that broke easily. NOTE: to installers. Do Not Over torque!! It will increase your chance of splitting hub.
