It's light, compared to a standard MC21 flywheel, but I wouldn't necessarily expect it to be a significant improvement over a lightened MC21 flywheel unless the static timing is the same (or better) than the MC21's.*
* I doubt it is, as it's designed to be used in conjunction with the HRC card and PGM-IV ignition, but this is pure speculation and until someone tries it on the dyno, is my best guess!
Too light on the flywheel also isn't necessarily a good thing, unless you are God on a bike! I was able to out-drag Steve's F3 on a few occasions (with the "old" F3 setup) as the inertia from my heavier flywheel (and a little bit of a weight advantage, so he claims!
