I believe so, but no direct experience. For what it's worth, my 2006 is far better than the 2004 I used to have, to the point where I don't see any need to modify it. It's a little chunky off idle, but nothing you can't ride around and call it character. I think Yamaha improved the ECU over time, and I'm told that by 07 they had it sorted on the R, so I would reckon a 2011 would be fine. At least, that's how I would be approaching a possible purchase, i.e. not worried in the slightest
