XS650 Forks + Retaining original spoked wheel
« on: March 09, 2019, 04:43:27 PM »
Hey folks!  Been awhile since Iíve posted. 

Iím upgrading the front forks on my Ď75 500b to XS650 units to include the upper and lower 650 triple. I want to retain my original spoked wheel and see that there is a 10mm greater spacing. 

A few questions about how to handle:

1. Can I use my stock axle or do I need to use xs650 axle? (I am assuming I need the XS650 axle)

2. Do I need to shim the wheel on the axle to account for the 10mm difference? (5mm each side) If so - how to handle the speedo gear?  Iím gonna delete the mechanical speedo if that helps with an answer.

3. I see in prior posts that shimming is required at the calipers - 5mm on each side.

1. The XS650 axle would be the best to use but the 500 axle which is the same as an RD350 might just be long enough if you use a thinner nut and you don't mind the other side being flush with the axle clamp.
2. Yes, unless you go to a 650 or TX750 front hub you will need to shim 5mm on each side and 3. shim the calipers also.
 
Personally, I'd  find a cheap 650 hub and lace it up to avoid having to do the shimming. You can also just gut the speedo drive unit and leave it as a spacer that way with no swimming required.

Thank you. That is the confirmation I was looking for.
