The picture
Street Triple: a strong MOT record by UK norms
Across 2,800 MOT tests, the Street Triple returns 88.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is audible warning not working. Tyre tread under the limit and a non-functioning shock absorber round out the top three. Average tested mileage sits at 17,828, 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?
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.
If you own a Street Triple and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
