it sounds more like a mechanic screwed up..

i once clipped a curb with a sidecar wheel while making a tight right-hand turn during a test ride... it was mounted to a nearly new 1500 gold wing.... luckily, there was no oncoming traffic, and i knew enough to turn into the roll direction.... but it was close... real close... felt like about 45 Degrees lean before recovery... with a whallop... Jim (Service Manager) spotted the scuff mark on the SC tire sidewall... he just shook his head, told me to check the bike's lean angle, and went back to work...
