Looking to replace a 17 RCS. By the end of a session on a CBR600 it's coming back to the bar on me. The 19 should hopefully remedy that issue for me. Throw me a PM if you have one for sale. Thanks
So you know the diameter of the pistons on your calipers? (It's easy to measure them if you don't) That is what should drive the size of the Master cylinder you are using.
