Early Headstock Bearings

Yorkie · Dec 5, 2022

I’m building a ‘70 S and there are no headstock bearings in the frame I’m using. The AN ball and race items are expensive so I was hoping someone could recommend a tapered bearing replacement I could use. I also believe I need to add a 6mm shim to the spacer tube, correct? Thanks.

If they fit, I have one pair of GBM 30205 "ISO9001" tapered bearings new that you can have for an address.

1969 commando Roadster steering yoke bearings

It's been a while since I messed with these because well, it was giving me a bit of a headache. New roller bearings from reputed british parts shop. Installed them and bolted yoke together. The bearings sit proud of the neck. Should I just roll with it as is? or buy thinner bearings? if...

I couldn't find a tapered bearing thin enough so I used a ball bearing 25x52x13 mm. SCO5A51CS24
Yes you will need a spacer.
