Update: 4/5
Today I began work on getting the steering head bearings ready to install. My plan is to get the front end all bolted on this weekend, which looks like it will happen as the UPS tracking says my wheel should show up tomorrow :-D
The stock GSXR bearings are ball bearings set in a plastic ring--Teflon I'm guessing. I'm surprised that this type of bearing would be used in the steering assembly, as it doesn't seem as strong as a Timkin type tapered roller bearing. The new bearings are KML Timkin type and the seals are Clark Seals Ltd (CSL). Bellow I have listed the KML bearing and CSL seal part numbers. I bought the bearings from
All Balls Racing bearings and components. Kevin Kraft is the salesman and he is extremely knowledgeable and helpful. If you every have any bearing needs, I would highly recommend All Balls. If you don't go that route, a good parts house should be able to either get KML bearings or can cross-reference the part numbers to Timkin or another brand.
KML Tapered Roller Bearings and CSL Seals:
Top:
Bearing: CR-0643
Seal: CYE-M320/28X
Bottom (Same size as GSXR, just Timkin type):
Bearing: 32006X
Seal: CY-32006JR
I have attached a picture of the new bearings compared to the stock GSXR bearings, and also a picture of the GSXR lower bearing race which was a PAIN to get off the steering stem. I ended up carefully grinding one side flat until I could crack the race to loosen it up.
