The MADNESS Lightweight Pulley!

This pulley is designed to give your 500 a boost in performance by reducing rotating mass of the factory pulley.
Unlike other designs this pulley features a wavelink design. The new wavelink design virtually eliminates flexing between the two pieces at higher RPMs. The new wavelink design also eliminates the possibility of the two pieces coming apart at high RPMs. Take a look at the product pictures and see the difference in the design for yourself.

Curious, why call it an underdrive pulley when it is the same diameter and uses the same belt? Am I missing something?
Having said that, it looks like a really nice piece; that weight saving will make a difference. It is on my Christmas wish-list!
