Hey to all you pre-2007 600rr owners out there. Just wanted to say i just finished retrofitting an R1 radial master cylinder and steel braided lines onto my bike and the difference is amazing! I can stop most of the time with just 1 finger on the lever where before sometimes i was using 1/4 to 1/2 the lever travel without any of the sensitivity this one has. It looks way better too without that ancient blocky style MC on there.
For those that don't know an R1/R6 radial master cylinder is a direct bolt on upgrade as well as the 07 and up 600rr's that come stock with em. It provides better lever feel and overall cool factor
