All calipers are a direct fitting mount and require no additional brackets.
They are individually designed to fit your particular bike. Each calipers is fitted with six seperate brake pads as opposed to the more common two-pad design of other four and six piston calipers. With the exception of a few Honda and Triumph models, there is no need or advantage to changing the stock master cylinder. A polished finish obviously requires more thorough and frequent cleaning. Most riders today are only concerned with increasing the Hp figures so they can go as fast as possible.
