Wow....gr8 upgrade there buddy....I also want to upgrade my stock braking setup on my 2017 RC390. I would like to get a better caliper and a master cylinder but should not break the bank[emoji23].....do you have any suggestions?Zombie thread revival time, I installed an R6 master cylinder on my ninja 250 coupled with a 4 pot radial calliper. Uber awesome feel and one finger braking. I’m sure this would be a brilliant replacement for the stock master.
