Pretty sure Morley sells OEM bearings, check with him. I usually go with Yamaha OEM for things like this....they're such a pain in the ass to change I'm reluctant to use an unproven brand, might bite you.
I only sell OEM bearings. Had a customer send his triple to me to repair along with an "All Balls" bearing kit. Had to remove and destroy his lower bearing that came in the kit since it bound up when it was installed. Put a new OEM unit on and it worked perfectly.
Yea, round it up to $80 with shipping. Email me directly and we can get the rest of the info we need to get you taken care of. I have them on hand too which many dealers don't have.
