The electrical wiring harness near the steering head and headlight bracket area of my 2018 Triumph Street Cup has worn through its protective tape, and bare wire is visible. I took the motorcycle to an authorized Triumph dealer because I felt increased resistance when turning the handlebars. The technician confirmed the cables are rubbing and worn, and told me this is causing the steering resistance and could lead to electrical failure and a crash. This puts my safety and others' at risk, because steering resistance or electrical failure while riding could cause a loss of control. The motorcycle is available for inspection. I saw no warning lamps or messages; the first symptom was steering resistance. When the wear began is unkwown, probably since day 1. The dealer told me a safety recall exists for this issue on 2018 Street Cup models. Triumph told me my motorcycle has no open recalls and to see my dealer. The dealer quoted about $1,000 in parts and 9 hours of labor. Other owners online report similar cable rubbing on this model. I am concerned the recall is not showing for my VIN and other owners may be unaware of this safety issue. The dealer's written repair order is available on request.
