In terms of raw performance, these two are evenly matched. The RS 660 Extrema and GSX-R600 produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. When it comes to agility, the RS 660 Extrema has a clear advantage. Weighing in 7kg less than the GSX-R600, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: It's a close call. Choose the rs660 if you prefer its specific styling and ergonomics, or the gsxr600 if you want the alternative brand character.
