Re: R100R fork brace

Thanks for your reply gspd and yes all it does now is secure the two part fender/mud guard.

R100R fork brace

Was surprised to see when striping the front end of my R100Rr that the fork brace was secured to the fork legs by 4 pin fixings through rubber bushes and held in place with sprung starlock washers.

Re: R100r Classic side stand

Tried your technique but still feels precarious and requires further work from me. Looking at some older American forums, who also complained about this feature, an industrious individual manufacture a Surefoot style stand mounted close to the footrest. Not one of BMW's better ideas mounting the sta...

R100r Classic side stand

Am pleased with my recently acquired Classic except for the sprung loaded side stand. Am 5foot 10inches of normal build but cannot fully extend the side stand with my heal and placing the bikes weight on the stand before dismounting. Would like to retain the stand with the auto retract feature. Any ...
