I have a 750X DCT with stock sprockets and 20 inch MadStad screen. With a light front breeze, mine does 110 mph max. It hits 90 mph quite fast, but any further increase takes some patience (which I don't have in general). Upto 80 mph the bike's rides wonderful, no need to go any faster anyway. It's more useful to have good torque and overtake vehicles without lag, than to have high end speed. My oppinion.
