The 2nd Gen are 3-pad design vs. the 1st Gen 2-pad.
There are many Suzuki models that share the same 3-pad brakes, including the Hayabusa and some GSXR's I believe.
However, I personally would invest the money in stainless steel brake lines and good (Carbone Lorraine or DP) brake pads. Your 2-pad brakes with those upgrades would be better than my 3-pad 2nd Gen brakes without 'em.
