Thruxton: a strong MOT record by UK norms

Across 2,842 MOT tests, the Thruxton returns 91.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-conforming number plate. A missing rear reflector and headlamp missing, inoperative round out the top three. Average tested mileage sits at 8,894, 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 Thruxton?

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 Thruxton 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.
