master cylinder / reservoirs ??

Hi trevor, you can fit any master cylinder you want, providing the piston diameters are the same, and I would stick with the radial design. You can fit master cylinders with different sized pistons if you want, but it will change the charachteristics of the brakes. Bigger pistons give more brake power with more presure, but less feel, and smaller pistons give more feel for less presure but more travel on the lever. So I would stick with one that has the same piston size. You could look for a Ducati 999 master cylinder, it's radial, looks verytrick and has a beutifull triangular resevoir built in, i bought one for £60 s/h for another bike I had, but I would check the piston size first.
