Any performance differences between Stainless Steel, Aluminum, and Chromoly? I not Aluminum is the lightest, then Chromoly. And longevity is steel, chromoly, aluminum. Now is the really a performance difference if I got a CHromoly or aluminum over stock? Rocky is having a sale and I may get one if there's any benefits to it. Thanks guys.

 

Do a search. I know there is some info out there because I just posted an answer to the same question today in the yamaha forum. I think it was called something like raptor gearing.

Basically just go with the steel.
