This creates a simultaneous, severe fire hazard directly over the hot exhaust. Prior Actions & Context: KTM previously acknowledged manufacturing defects on older models under NHTSA Campaign Number: 17V388000.
This puts my safety at risk if I experience a crash or collision since the integrity of the tank is in question and it puts others safety at risk because it could rupture from a fall and cause a fire.
This should be a recall and the tank should be replaced by Ktm to prevent a potential fire hazard and or injuring the operator severely.
