I have the same problem - also with a 2011. It basically sticks at 1900-2100 RPM. I have to really open the throttle to move past that point, and then (with the throttle at 40-50%), the bike surges. It makes it almost impossible to ride in the city, and it's been in and out of a shop for the last year trying to find the issue.
So far they've tried checking the tune, sparkplugs, cleaning the injectors, and cleaning the throttle bodies.
No improvement, so I've taken it to another shop - I'll report in if the new shop is able to isolate and fix the issue.
