To all of that, I'll add this: I sat on and sorta measured up on all the 1L bikes and the ergonomics are far best on the RR.
And that transfers right to street riding comfort. RR like the other reviews say handles like a 600 cc bike or better. Just point and shoot wherever you want to go.

My dream bike is an 04 R1. I saw it in the 8th grade and creamed my pants.. I wouldn't buy either of those bikes.
