Dyno Chart
The 113-hp R6 is amazingly strong for a 600, but keeping it above 10,000 rpm is an amazing amount of work. The GSX-R600 punts Honda's more linear CBR, making it the most rideable 600. Triumph's 675cc triple trumps Kawasaki's 636cc four with a broader spread of useable torque. Surprising no one, the GSX-R750 positively annihilates everything else, proving once and for all that there's no substitute for cubic centimeters.
