Ok - mine was changing the rear tire on my 2015 F3s. I was lowering the Spyder onto the rear wheel with my ATV jack when I released to quickly and the Spyder bounced off the jack causing the rear brake mounting plate to hit the speed sensor damaging it. (I did not know it at the time). Put everything back on and went for a ride - or tried to. Spyder would not shift and got limp home mode. Had it towed to my dealer to get it fixed. Cost over $270.
