So I've managed to snap off one of the posts in the CRM's inner clutch hub.... Great job I know ha ha

Is anyone aware of any alternative hub that works? I know the CR's seem to use 6 posts so probably are out of the question but crf perhaps? The only 2nd hand one I can find is extortionately priced!

I can't repair the old one by bolting through from the back either as not only did the post snap off but it's also split down the centre!

the part number is 22120-KAE-010, you could try an internet search. i found that it's the same as used in a honda trx250 quad bike viewtopic.php?f=6&t=7626&hilit=moose+racing

No it is not the same as the TRX one. Look further ............ and read more please.

Clutch baskets are interchangeable between all Mks of CRMs. They frequently come up on ebay. You should be looking at paying ~£30 for one.
