Well, the radial front brake MC (from a 2005 ZX-6R; a Nissin and 3/4 piston diameter, had been led to believe it was 11/16 diameter... oh well) is on. It took some fiddling (had to modify the reservoir bracket) to get it on but the result is well worth it. Stopping power and feel is much improved. I recall from looking into the matter that I beleive it is similar in geometry to a Brembo 19 x 16 (although being a stock piece it is surely not in the same league quality-wise) but power is incredible. Lever travel is a bit more than the SP-2 MC I had on before (which had a 11/16 piston diameter) but the power is significantly improved (meaning VERY strong). Overall, it was well worth the effort and expense (icing on the cake to the other mods I performed).

cheers
