Two years into XB-12R ownership. Close to 10,000 miles, about 4 track days and not one problem. Changed the oil every 3000. Belt is good. Speaking of stoppies though, this bike has a short wheelbase. I've flipped it going into second real hard, and my son flipped it the other way making a panic stop in traffic. Both rider error, but although the bike isn't especially fast, it's an expert bike in my opinion. It crashes good too, and the parts are very reasonable
