790 Duke 19: a strong MOT record by UK norms

Across 590 MOT tests, the 790 Duke 19 returns 88.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is uneven braking force. Tyre tread under the limit and a non-conforming number plate round out the top three. Average tested mileage sits at 6,447, 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.
