RS 660 2026 vs GSX-R600 2024

In terms of raw performance, these two are evenly matched. The RS 660 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. Both bikes share a similar footprint on the scale, with only a negligible 4kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. 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.
