well I would say you'll have a big grin if my demo rides mean anything - my Roadster's due on 1st april and I KNOW it's going to be fun. i'd never ridden a Rocket before, but this one has got me hooked! It just takes off from 1500rpm and growls (with TORs fitted) , never mind opening up at 3000+ rpm.
I don't know how the performance compares to an original R3 yet but look forward to riding with my mates (no Rockets there) on some good roads.
My Sprint ST is a great bike but the Roadster's on a different planet!
