I bet it could wheelie before!:devious
if you've ben ridding a while you willknow that early 90's kawasakis had alot of lowend power especialy the zx6and7 were very snappy in 1st and second gear w/a pipe & jet kit this 07 zx6 cant compare to them w/low end power top is a differentstory though..Your 07 zx6r could always wheelie.
All you do is figure out your sprocket ratio compared to the new one and apply it to your rpms at whatever speed you want to figure it out for. It's not exact, but it gives you an idea.intermission, u mind sharing how you went about doing that math to calculate those numbers? kinda curious..
