OVER TIME, THE TURN SIGNALS STOP WORKING BECAUSE OF HOW TIGHTLY THE WIRING HARNESS IS TO THE HEADSTOCK. BECAUSE OF THE OVEREXTENSION OF THE WIRES, THE CONNECTION FOR THE TURN SIGNALS BEGINS TO BREAK THUS CAUSING DAMAGE.
Triumph Motorcycles America, LTD (Triumph) is recalling certain 2016-2019 Bonneville T120 and Bonneville T120 Black, 2017-2019 Bonneville T100 and T100 Black, 2017-2018 Street Cup and Street Scrambler, and 2016-2018 Street Twin motorcycles.
