Country	Japan
Category	Automotive
Published	2026-04-28
Country of origin	イギリス
Manufacturer	Triumph Motorcycles Japan Ltd.
Models affected	Bonneville T100, Street Twin, Street Scrambler, Bonneville T120, Speed Twin 900, Scrambler 900
Units affected	3753
Defect	In the connector terminal connecting the generator-side harness and the main wire harness, due to insufficient design consideration, the plating on the surface of the terminal may wear away due to driving vibrations, etc., exposing the base material, which can oxidize and corrode. Consequently, the connector terminal generates heat due to poor conductivity, and if use is continued, in the worst case, the connector may melt and cause a fire.
Component	Electrical system (connector terminal)
Remedy	Abolish the connector connection between the generator-side harness and the main wire harness, and fix the wiring using a dedicated fastener.
