Newer 600's produce 110+hp, and weigh less than 380lbs. My old 600 probably makes 85hp and weighs over 400lbs(still has a steel frame, not aluminum). My old dog will "do" anything a newer bike can, just not as powerful or quick out of a corner.(my brother owns a 01' GSXR750 and burns me out of a corner every time, but in corner I hold just as well and my bike is 6yrs older)
