Hi Skooter.
I can sure try. Most of the aftermarket stuff is for the MC21 and 28 but I sometimes come across used stuff. For new parts I have half rear sets, heavy duty clutch cables, fork braces, alloy or carbon fiber clip ons, billet levers, sprockets, clear lens covers, dress up items, floating buttons conversion kit (for front discs), pads, braided lines and new Brembo caliper adapter brackets for MC18.
I also believe I know of a used but good condition MC18 rear Magtek (Gold) for sale (18inch). If you have a look into my website and check out the parts shop you can see some pictures of the parts I am talking about.
Thank you
