Need an RC51 master cylinder in very good to new condition.

 

SP1 or SP2? they are different

 

I have a 2000~2001 SP1 brake MC in great shape for sale I guess...

 

Crap, I'm not sure I'll have to measure the caliper pistons.

 

I have one as well - not sure which era. I suppose the piston diameter is whats most important and then to preference in terms of other features they might have added.

I can take a pic and send to you if relevant. let me know by pm

bil

 

u can look up piston sizes for anything
search this forum for the thread that exists
but either sp1 or sp2 mc will work for example the rvt/rc calipers, cbr600f4i, cbr900, etc
its the feel u want
i've tried both on the sp1 & cbr600 calipers and there is + & - for the -1.5mm difference in these 2 mc

 

The diameter of the piston is stamped into the body on the master cylinders, so you should be able to identify yours that way cliby...
