I read a couple discontents with OEM mirrors on the site and kinda agree to the point that the aerodynamic shape and position are better on the six-fiddy. However in the following video there's some interesting mod that in theory should move standard 400's mirrors more to the aerodynamic shadow at that reducing the overall machine width. I hope everyone knows what i'm talking about
