In terms of raw performance, these two are evenly matched. The Ninja ZX-6R and R9 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 3kg 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 zx6r if you prefer its specific styling and ergonomics, or the r9 if you want the alternative brand character.
