Different type of bike... different class all together. Besides.. the ZX10R will not touch a ZX12R or Hayabusa in 6th gear.... no aero's.
The ZX10R is a Superbike class machine made for doing everything well.
The ZX12R and Hayabusa are Hyperbike class machines made for high velocity racing.
Like it or not... there are only 2 bikes that still have plenty of juice in them after 180mph.... and the ZX10R isn't one of them. The 10 is quick up to 4th gear and great in the twisties... but on open highways... it doesn't cut the mustard in 6th.
My bone stock untouched motor ZX12R with just a pipe, gearing, and remap went 199mph on GPS in roughly 1.25 miles. My buddy's identically modified ZX12R.... went 199mph on GPS as well. Hell, with a little more fine tuning they both could have gone 200mph on untouched motors.
Can you say the same for the ZX10R or any liter bike for that matter?
