Alternate Master Cylinder

Postby tunaboy » Sun Mar 10, 2013 7:01 pm

To improve brakes on 1000 and 1100 wings swapping out the stock master cylinder for one with a 5/8" piston is supposed to help a lot. Anyone know which bikes Honda built with a 5/8" piston? Yes I know that it would be a metric size close to 5/8".

braided brake lines and sintered brake pads make for some very good brakes 8-)

The 81-82 GL500 Interstate (dual caliper) used a 5/8" MC. 5/8" is stamped on the bottom.
