I just installed a Brembo radial clutch master cylinder off of a 2009 Ducati 1100 monster. The ratio has been improved slightly with the Brembo have a 1mm smaller bore 15mm vs 16, for less effort and more feel, with a wider friction zone. I already had 100 pound Barnett clutch springs, so the lessened effort is a god send. As an added bonus, the previous owner had 6 position adjustable levers already installed, which can adjust the friction zone from at the bar to about 1.5 inches off of the bar
