Hi everyone.
someone knows if there's some brake master cylinder with 19mm diameter that is compatible with original brake lines & handlebar of the griso 1100?
aftermarket or original equipment of another bike.

I'm thinking about replacement because original one seems to me a little undersized (i think is 16/17mm)
 
All you have to do is look in the STORE here------------------------------------

16 mm. Use a small mirror, it is printed on the underside of master cyl. I have two. Perfect bleeding is a necessity to get a decent feel, otherwise they can be spongy/long travel. Aftermarket will make them better (I am "used to" mine), but proper bleeding is always the challenge. After a recent caliper re-build (splitting the calipers) it took a couple of days of bleeding/waiting/re-bleeding to get it back to normal.

thank you for the infos, the line extender can be a solution though i don't like it so much.
Anyway i've to change all the fluids prior to make a decision. Now the bike have a decent power but usually i prefer a more aggressive feeling under the lever. :)
