Defect: Triumph Motorcycle America, LTD (Triumph) is recalling certain 2019-2020 Street Scrambler and Street Twin motorcycles. The wiring harness may have been misrouted, allowing it to contact the lower lug on main frame headstock.
Risk: Contact between the harness and the headstock lug can damage the wire and cause the engine to stall, increasing the risk of a crash.
Fix: Triumph will notify owners, and dealers will apply a new VIN label protector to prevent wiring harness damage, and, as necessary, damaged wiring harnesses will be repaired or replaced, free of charge. The recall began August 28, 2020. Owners may contact Triumph customer service at 1-800-232-3780. Triumph's number for this recall is SRAN 584.
