I'm looking at replacing the master cylinder on my NC30 to get something with an integrated reservoir for a sleeker look. (plus my M/C is old and ratty)
I want to maintain the correct hydraulic ratio, so can anyone tell me what the piston size is in the NC30 Master Cylinder?
If you like, you could also tell me what is interchangeable... :)
Not looking to switch calipers or upgrade as I reckon the standard brakes are fine. Plus I just bought funky ASV levers or else I would look at some bullsh*t-expensive Brembo radial...

I seem to recall that the standard master cyl is 11 mm?

Are you gonna go for a naked style master cyl? Can't comment on compatibility, but I know that some naked Hondas run different levers to the usual Honda sprtsbike stylee.

NC21 brake resevoir is all in one and it shouldn't be too far off. I know theres a few on ebay for pennies.

86-96 VFR750F? RC24/RC36

Same lever as the VFR400 although I'm not sure about the bore.
Don't have a clear shot of just the M/C but these two show it.

Apart from the original Nissin pads which would anybody recommend for track use using the standard calipers?

If occasional track use then still OEM Nissin, never been out braked yet! :D

Dunno about regular track use but I've heard good things about about bendix and they work a treat on my SV.

Thanks for the info.
There are several compounds available from Bendix - do you know which one it might be?

My SV is fitted with
BENMRR186 BENDIX SUPERSPORT RACE BRAKE PADS

They are the pads I was looking at. Might give them a try.
