I fitted the taper roller type to mine and it works just fine after some initial problems of the top clip touching the headstock......What a riding experience that was It felt like either the rear wheel had come loose or a rear puncture When I finally realised what was going on, I lifted the top clip off again and spaced it up with a thin washer. Clearly a warning I ignored about checking that the bottom of the steering stem and the top clip are free of the headstock. Ron

Then again, replacing the original ball bearings and cleaning the races is much easier and requires less periodic adjustment. Sometimes new races are needed depending on the state of wear. Luckily, the WM20's like many older brit bikes can be lubricated through external nipples, unlike newer metric bikes (>1970) which require a complete disassembly of half the machine.

I agree with that Cas! If only the balls need replacing. Invariably though, the cups are rippled Ron

I use sealed ball bearings which need no adjustment and very infrequent replacement...

Ball bearings were fitted to Norton Commandos and Buells as original equipment (and others probably...)...Ian

AH!! Isn't that what I had from you Ian? Not the timkin type at all. Yes I remember now sealed ball races. Never need grease or adjusting. Ron

The bearings was a 1 inch x 2 inch Ron, KLNJ 1 - 2rs is the correct reference, Japanese 99R16 or just R16 sealed.
I have some if Ian has not got any, but try Ian first :-)

Hello Ian, I would be interested to have it for my bike that has the fork that swings in braking. Could you contact me by email? Thanks in advance. Daniel

Ian, do you have any of the head stem bearing sets available and will they fit the tele forks?
