I have a 2012 Xciting 500Ri, it has almost 1200 miles, everyone I put on it. The rear end on the left is starting to growl on take off! Sad, I've never abused the vehicle. Never tried any burnout, just take off and stop. Sucks, I won't be buying another one of these. I'm going to stick with Honda, I know they work. Sorry Kymco, I don't have time to run in and give up my scooter every time something goes wrong. So sad. Won't see me doing the Kymco cheer for you.
