I've done few laps on the 2009 R1, but no street riding. I got to tell the sound that engine is awesome. It also pulls incredibly well

I literally pulled back into the pits after 2 laps (that's all that was permitted) laughing and giggling inside my helmet. I'm way past having a liter bike as my only ride and I'm not even sure I want one as my 2nd bike any more. BUT... if I was going to pick a liter bike, I would consider this to be on the VERY Short Short list. The only other 2 I would consider I haven't even ridden (RSV4 & 1198S)
If it floats your boat, I think you should pursue it! Helibars and a custom seat and you might do just fine. I used to tour on my 2000 R1, it wasn't bad... but I was a little tougher back then.....
