If straight-line speed is your priority, the Ninja ZX-6R takes the lead. With 7 HP more than the XSR 900 GP, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 2kg 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 xsr900 if you want the alternative brand character.
