fork pre-load spacer
« on: October 03, 2016, 01:02:57 PM »
Hi guys i'm in process to redo the front fork of my R65 (1981) after changing the rear shocks.

I disassembled legs and in process to rebuild them. I want to lower a bit the fork and read something that people first removes the "pre-load" spacer.

Any comments ?

Other ideas to lower the fork (1" to 1"1/2 max) ?

Thanks for time

Guyom.

I think the preload spacer that is mentioned in other posts, is a spacer made from PVC pipe, it usually is used in conjunction with aftermarket  ' progressive ' springs, which are usually shorter  in length than OEM springs .

There are no preload spacers with OEM springs .

No pre-load spacers with stock forks. They might possibly have been added if the previous owner was well above average weight.  

Rather than compromise the fork travel it might be better to re-position the stanchions in the clamps but 1 1/2" is a awful lot to lower the bike and it still be safe.

The position of the handlebars, being directly above the fork caps, would prevent moving the forks higher in the triple clamps; unless someone plans to attach clip-ons to the fork stanchions.

I'd be very hesitant to lower the R65 too much, if in fact, at all. They were designed form the get-go for the rider who was a bit shorter in the leg and the fork tubes are already much shorter than any other airhead. I foresee problems with center and side stands if it is lowered further, along with the risk of pounding the sump into stuff.

Altering the location of the stanchions within the triple trees will also alter the handling Quicken it up. Perhaps too much.
