I'm putting together motard brakes on my Aprilia RXV for Rally racing. They need to be good but I'm not spending big bucks. I have a friend that has a salvage business dealing in late model sport bikes. What model bikes have a good stock master cylinder?
Later model Kawasaki, Suzuki and Triumph all use Nissin master cylinders and the levers are all interchangable. I know the Yamaha ones are different not sure about the Honda one. I would use one of them since they are all radial and pretty easy to find at the track if you break something.
i used one which if i remember correctly, was off of an 03 ZX-6R. tons more brake than you'd ever need. in fact, it's for sale, with shortened lever and braided line(i parted out the rest of the bike).
