Like the title says, anyone try it? Upgrading their 04-06 cbr1000rr master cylinder, to a 04-06 R1 M/C??? I know it will work, I'm pretty sure they are better and I have one! If They are a big up grade all use it but I thought I was gonna use it on my 04 ZX10r. It ended up having a After market Brembo on it all ready.... So, It's sell it, return it or use it?!?!? I know they work Great on 600rr, ZX10r and GSXR's but the 1000rr one's not as bad as those one's and I need better calipers for my ZX10r. I guess, I could steal my 1000rr Calipers till it's done but I want ZX14 calipers or later zx6r one's. So I'd give my 1000rr one's back when I got some others.
