R1/R6 Front brake master cylinder on a FZS 600?

Greater choice of levers, slightly larger MC so increasing feedback in braking and it looks cool.  mokin

Wrong way around mate. If you get a bigger m/c piston then you'll have less travel on the lever, and a more wooden feel to it. It's the smaller pistons that give more travel and more feel. With a smaller piston you also don't have to squeeze the brake as hard for a given level of braking.
