Fly Wheel Question

[Vital]

How much lighter is the WR450 flywheel then the YFZ450 quad flywheel? Anyone know?

They are the same. Go www.trailtech.net

I was checking out the site today. I can't decide whether to try the -4oz flywheel and revbox or just spend the $650 on the whole crf conversion for my wifes 450R. I haven't really been researching prices yet but I think it will be real close in the end.
