Im not sure what caused it but when j was riding my motorcycle the seat got hot ajd when I looked down I saw orange flickering so it caught fire while I was riding it and I had to safely slow down anf get off it. It should be able to be inspected. My safety was at risk cause my bine was on fire and im lucky no one else was near me driving at thr time or im lucky my partner wasny on the back of mu bike while it spontaneously combusted. I had under 1500 miles on it and no eletrical upgrades. Im not really sure if it been inspected bu the manufacturer the manufacturer has denied warranty claim caused they cant confirm a manufacturer defect. I think progressive is inspecting it very soon if not already has.
