Yeah, the 06/07 cranks were made heavier to handle the torqe/power easier and not want to wheelie so much, then in 08 they made the crank lighter, but remained the same rotational inertia. I say make that shit as light as possible and let her scream...
It should be the same as in bigger motors, such as V8's. A heavier crank/flywheel makes a much broader spread of torque and power where a lighter one might make more peak power and a more inconsistent curve. Now I'm not sure that was necessarily the truth, because dyno graphs were compared with "supposedly" stock bikes and the 04's power curve was much more favorable. It does not mean that the 06/07 is any slower, makes less power, or is any less of a threat. Just helps keep the wheel down and in certain instances will make the bike faster. All in the nature of a beast, and with that said there is no taming a ZX10R.
At its core, the Ninja ZX-10R is a motorcycle built for the accomplished rider who can fully appreciate its capabilities--whether put to the test at a racetrack, or merely the focus of bench-racing conversation. It is, by all standards, the embodiment of the ultimate superbike.
