    It"s been too long for that. But rest assured most motorcycle rear master cylinders can be easily adapted, just look for the right bore size. I ordered a Brembo one that looked right and it damn near fell into place.
    If you want something that literally bolts on, maybe Chickenstripn can help with a part number?

    I found another thread about master cylinders where someone used the brembo PS11. Had a lot of links regarding MC to caliper ratios to back up why the pedal feel was so bad. Hope this helps!

    That sounds about right. ^^^ Thanks for the heads up

    The smaller MC bore does the same exact thing a larger caliper piston would do. You get more pedal travel and more pressure, IMO both good things for the Buell rear brake. You could get a bigger caliper, or change the pedal ratio for the same result, but the M/C change is cheaper and easier IMO.
