Street Triple R: a strong MOT record by UK norms

Across 1,703 MOT tests, the Street Triple R returns 87.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Audible warning not working and a non-conforming number plate round out the top three. Average tested mileage sits at 16,414, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Street Triple R?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
