You really need to be concerned with only two things: will it fit, and 
will it work?


For the "work" part, you need to pay attention to the m/c diameter, 
which is usually molded into the outside of the casting. Oddly, it's 
often in inches instead of mm.

The same diameter as a stock GSXR m/c will work just like the stock GSXR 
brake system. Smaller diameter m/c will give more leverage for lighter 
feel with longer lever travel. Larger diameter gives less leverage 
requiring a harder squeeze.
