I bought my bike at 5100 miles back in June. 2013 model. Long and complicated explanation short, the bike was a dealer demo, with a warranty through October 2016.
I can imagine since it was a demo bike, any of the failures that could have happened have already happened and been fixed. Shortly after purchasing, I had a few things warrantied at a different dealer:
New pannier bags (seams were pulling, never been overloaded. They were replaced with the newer style bags so this wont be an issue)
New front rotors (warped, I bought and installed my own galfer HH pads)
New headlight housing (small melted spot, I think the high beam was left on with the bike parked)
New throttle and sensor (Recall issue. standard procedure for most of us)
After about 4000 miles, I have fallen in love with this bike. Only a few minor issues to speak of:
One of the centerstand bolts worked itself out, and the spring holding it up snapped. I had to ziptie up the stand to get myself home (150 miles). Also when replacing the license plate light, the clear plastic cover snapped. $30 to fix both those issues, wasn't worth the 100 mile drive to the dealer.
Overall I am happy with the reliability. I really have no idea what was and wasn't done during the first 5100 miles as a demo, but the last 4000 have been pretty good.
