The "R7" is not as "exciting" as made out to be. It's a warmed over MT07, really. Coming from a 400, it's going to be great. Coming from a 600, it's not going to be so great, IMO.
The Aprilia 660 is the one to move to from a 600...but still, much slower, etc. Great chassis however. It'll be interesting to see the R7 compete against the 660 and like every year; Yamaha will throw coin at their program and Aprilia will watch from the sidelines.
Not really. You just need to know the right people...and have them like you!
