It happened to me a couple of years ago on a day rental in Eimeldingen Germany after only two hours of riding.The dealer not only return my rental fee but also gave me, at no charge, a new pair riding pants and boots, both high quality gor tex items. I had a major "Ahhh shit" moment when the rear wheel 1st broke loose but the support I got from the dealer, Renner Motorradhaus, was beyond my expectation. Oh, and they had my oiled/soiled pants cleaned and shipped to me in the US.
