Try to measure the one way bearing. On my 2017 cf 520 (500s for you in the us) I measured the one way bearing and it looked like it had cvtech trailblock standard measurements for one way bearings.

Just on CVTech website. No listings for one way bearings. Update: Ok, just found it.

Do you have the measurements and picture? Mine is also 500. Still using bike, so don't really want to take it apart til I get one.

I just googled the part number and there are plenty of places in US advertizing them. Listed as 35x47x7mm deep groove bearing.

NTN 6807LB. These are only the two removable bearings in the sleeve. This is not the complete one way bearing.

So, I refuse to pay $433 for a GD one way bearing from dealer. Ludicrous. I tried couple local bearing suppliers but no luck. Got a few emails sent out. Waiting on replies. Took bearing out today, removed dogs from the one way center, packed the two bearings and reinstalled. No more engine brake, but as I said, not paying $433 just for that. One more nail in CFMoto's coffin for me.

Can't understand why they show you have to buy that whole assembly where others with the same setup can get just the one-way for about $104.11. Still too high but..makes me wonder of one of those would work....probably. I can't believe the Chinese would actually make something with enough differences that would force you to buy an assembly like that. They like to use one thing for as much as possible.


Wait...I see there is an option to just buy the overriding clutch...for $327 bucks!  That's pure nuts!

Byes, I think this one way bearing is only a farce. I refused to pay $450 for an engine brake convenience, so I took mine out and removed all the little(I'll call them dogs). The two bearings were fine so I just repacked them. Reinstalled everything and went for a run the other day. Bike works the same as always, less the noise. Engine braking works fine. I see absolutely no difference.
