An official CAA Japan notice concerns Motorcycles (Triumph Bonneville T100 and 5 other models) - Repair. Electrical system (connector terminals) defect. ■ Defective component: Electrical system (connector terminals). ■ Structure, equipment or performance considered noncompliant with standards, and cause: Due to insufficient design evaluation of the connector terminals connecting the generator-side harness to the main wiring harness, vibrations during riding and similar factors may wear away the plating on the terminal surfaces, exposing the base metal and causing oxidation and corrosion. Poor electrical contact may then cause the connector terminals to heat up. Continued use may, in the worst case, cause the connector to melt and result in a fire. Published 2026-04-28.
What to do now
Recall notification number: 外-4184. ■ Corrective measures: Eliminate the connector connection between the generator-side harness and the main wiring harness, and secure the wiring using dedicated fixtures.
