Vintage BMW Motorcycle Owners

Except for the faded paint scheme, a R100S is very similar to the R90S but doesn't have the cachet. The R90S was a 'Halo' vehicle. Changed the perception of BMW's from stodgy to Wow!

Of course, if you think new rings will improve the situation then you really have nothing to lose by trying that and seeing if it he...

As Kurt said; if you are replacing them, just cut them off.
OTOH if you want to reuse them, it is easier to remove the whole footpeg.

I've enjoyed your postings Mal. I'll gladly donate a dollar to help pay your dues. If everyone who wants to keep you around gives a dollar you will probably have a life membership.
