KTM is to recall all of its 690 Duke and 690 Duke R bike models manufactured since 2016. The decision came after the company found out that the gasket in the fuel tank filler necks is prone to fuel leaks. According to the recall notice, “Due to tolerance variations, the system comprising the fuel tank, fuel tank filler neck and fuel tank filler neck gasket may leak and fuel may escape. A new fuel tank filler neck with modified gasket that is leak tight has therefore been developed. The gasket of the fuel level sensor was modified as part of this, and must be replaced as well.”
