Here is the axle mounted 460 bike that's unpiped, with a piston skirt mod to match the transfers and lowstall clutch springs. Up against a ported and piped 460 on a custom full suspension bladez or evo I can't remember it was so custom lol.
I didn't have the motor long enough to have had the miss fortune of breaking a DDM clutch saver, but the clutch is so easy to service its a matter of carrying a spare set and a few tools in the go pouch " we all should carry on our MB's.
