So I have an 06 black 636 with 2k miles on it and thinking about jumping back up to a liter bike. Rode a buddies R1 Monday and though I love the 636 I miss the power of a liter. I have been eye balling the new 10 but havent really decided if I am going to make the switch yet. Most of my riding is track only so any one that can give some insite( I read all the mag input but I prefer "real" people reviews) on the bike I would greatly appreciate it. Also how much should I expect to get for my 636(stock except for flush mount front signals, rear light intergrater, GPR damper and Vortex sliders)?
