front master cylinder size?

[super jim]

Is the front master cylinder bore for the CBX same as the CB900F and CB1100F? I have CB900F rotors and calipers. I think I could benefit from a larger bore master cylinder as I have to pull the lever pretty hard. I expect the CB900F calipers have more piston area.

Both are 5/8.

Two things: As Dave said it is 5/8 inch NOT 16mm. Secondly, a larger bore will INCREASE effort ; not decrease it.

thanks. I guess I had it backwards.
