My clutch went out at 27,000. Whether or not you think that is low is up for debate apparently.
This is from my 09, although I am not sure if they got all the fixes in for to '10.
There is an issue (cosmetic only) on the seam around the gas tank. Not the tank itself but the plastic around it. Between the colored plastic and the black plastic cracks can occur. Take a look. They should replace it for free.
The wheel bearings are a known issue, keep an eye on them. Also should be replaced for free. My rear wheel bearings took a crap and destroyed the wheel hub. All replaced for free. That was at around 24k.
Chain and sprockets had a recall, although I am 90% that was first year only. no problems with mine but I got a brand new set for free at 18k.

Oil can seep out of the top end (very small amount) as the gaskets they had were designed poorly. This will usually happen after the valve checks. Also I think only a certain range in the first year. Easy fix anyway.
That's all I can think of right now.
