I'm replacing my front end with a trick 900rr front end with erion racing triples and oversize rotor kit from braking that I got from MCleather (Thanks Jay, he's a good guy). Anyways I got some triumph 955i clip ons to go under the triples now I'm just trying to decide what to do with the calipers and master cylinder. My options are as follows.
Calipers: stock, 900rr, F4
Master: stock, 08 600rr
So are the F4 calipers the same as F4i calipers? are the 900rr calipers the same piston diameter? is the rr master 11/16 (17.5 mm) if so is that going to leave good braking power? I calculated the leverage ratio of master area (assuming 17.46mm) to caliper piston area of f4i calipers at 28 this seems acceptable since stock ranges on sport bikes seem to be between 23 to 35.
