      Or this nifty little number from Ebay (suitable when running a single rotor)

      80 gs1100 16-v ported & polished, 1 mm oversize intake valves, 1150 carbs w/Dynojet stage 3, plus Bandit/gsxr upgrades

        I actually like all of the newer GSXR masters with the remote reservoirs. Then you can mount the reservoir however you need to just by making a bracket. Ray.

          If anyone know of a new 5/8" bore master cylinder that will take a stock Suzuki mirror please share.

                    Suzuki used 5/8" for dual disc, 14mm for single.

                      Maybe a naked Bandit set up??

                        Not an 82' 1100, but here is an 06'-07' GSXR 1000 Master. It has a 3/4 marking in the master cylinder casting. Be it 3/4" (19mm) piston, not sure, but it is for dual calipers. No mirror mount though. Reason I went this route was with the clip-ons, a slim starter kill switch, and push-pull throttle there was no room to mount a OEM master.

                        It bolts on to 7/8" handle bars, just need to make sure to use the correct banjo bolt.






                        Also for the masters with the mirror mount boss the main thing is the thread direction, L vs. R, that becomes an issue. I've seen adaptors and stand alone mirror mounts, but depends on what you are after.

                            Kawasaki Ninja (5/8" bore same as stock GS Twin Rotor)



                            GSXR Radial with 6 pot calipers



                            On the GSXR you can use the stock brake backplate (rider side of the bars) which has the mirror mount on it. The holes line up perfectly. You just have to be aware that the rider side is a little wider but you can even cut it down if necessary (I did in order to make it fit on the limited bar space I had).

                              3/4" bore (19mm) will probably work & will just require less movement at the lever with correspondingly more force required in order to activate brakes.

                              Stock is 5/8" (16mm).

                              Stock single is 14mm as Ed has said. Requires more lever movement to work the brakes. Works on a stock dual setup but I wouldn't use it on anything that has a bigger piston as stock (i.e. don't go using a 14mm as a replacement for a stock 3/4" piston master).

                              Personally I have tried the 14mm piston on stock brakes & didn't like it. Too much lever movement & felt "spongey".
