WTB RC51/ similar Master Cylinder
It may be a long shot, but does anyone have a Master Cylinder laying around or no longer need.
I bought RC Calipers and Russell brake lines and would like to complete the deal...
I have seen some on EBay, but wanted to check here.
PM if you have anything.
Thanks

I don`t have radial calipers but even with the stock 296 mm rotors, the 1998 CBR900RR calipers, braided lines, Nissin radial MC (from a ZX-6R) and HRC "hard bite" pads that I do have gives me braking that is exceeded only by a Ducati 1098 (in the bikes I have tried of course, and that list includes the new KM RC8, the Duc 848,and quite a few others; having spent 18 months as editor of a bike mag had its benefits)
Anyhow, I wish the dude luck in finding himself an RC51 MC (Note to self: why do I bother trying to give advice and help others anyhow???????).....

i have a 03' cbr 954 master:
https://www.superhawkforum.com/forum...ad.php?t=16649
i'm almost sure the cbr954rr piston/ bore diameter is 11/16th (17.5mm) which is the same as the rc51 SP2's(2003-2006) master. i can check later. The SP1(2000-2001) used a 19mm front master. The sp1's calipers had 34mm and 32mm pistons while the sp2's had 32mm and 30mm pistons. regardless it's an upgrade over the stock vtr master. the difference between master's will be feel and modulation.

close, but not quite.
929, SP-1 , 900RR (98-99) and F4i have same calipers (and 19 mm MCs, at least in the case of the first two) while the 954 and SP-2 share identical set-ups of their own consisting of smaller pistons in teh MC and calipers (same caliper castings and pads all around though)

And I am schooled by the brake-meister! Thanks for the info.
This much I can tell you...I had a 929 master and compared it to my SP2 master (when I had my 02 RC51) and they looked exactly the same and had same diameter pistons. Maybe I got a 954 setup...dunno, but I think I may have bought it before the 954 even came out. That was a long time ago....but I'm pretty confident that the 929 and SP2 are the same.

929 & SP1 is the same... 954 & SP2 is the same... Same years same parts... But the SP2 and 929 is not the same...
You know forks... I know brakes...
How much are you willing to bet...

Well, if it wasn't cold as *** outside and I could actually get to my bikes through the snow I'd go look and verify. Until then I guess I'll have to assume that I have myself a 954 master. 
this thread yet? hehe
