looking for Rotor

[Greg goes wild]

Guys i am need of some help. I have my bike in the shop for maintenance on it. The REAR rotor the shops
BMW say it needs to be replaced soon. They said the Rotor on the REAR wheel is the problem with side
kickstand NOT working is that right?? I saw a adjustment bolt below the below the Chain belt casing is that
to adjust the kickstand brake? cuz i have noticed it has not been working Can i buy a rear wheel rotor on
Amazon that is the same? PLUS i need a SHRINK front tire. The Mezler has cracks in it 5yrs old
I would really appreciate your help.

I can't quite imagine how a below-thickness-spec rear brake disc can interfere with the functioning of the kickstand brake.
I recently adjusted my kickstand brake because it was no longer holding firmly (likely due to the rear disc wearing, as is normal). Can't remember now how the adjustment works but it was very intuitive and easy/simple.
Get the shop to tell you what thickness the disc is, the shop manual has the wear limit specs we can look up. My 650 has 20K miles and I don't think (but haven't checked) the discs, front or back, can be worn enough to require replacement.
Be careful about buying aftermarket brake discs though; BMW uses a non-standard 'floating' system and aftermarket discs may not fit.

NO brake disc the Rotor cuz i do NOT know how much that would cost knowing
BMW probably $200 bucks. Disc was 4.15 from when it was newer 4.18. NEVER
replaced the discs on any bike i owned . Front tire size can't find it in the hand
book? 2 different BMW changed out the right front fork cuz it had been leaking
out the oil. that's $900 a pop n i am NOT going to have them change or replace
it. But i do NEED NEW handgrips. are there any aftermarket hand grips that
will work? i have the HEATED grips if that does make a difference?
