The picture
Across 2,272 MOT tests, the Interceptor Int 650 returns 91.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake efficiency below minimum requirement. Brake control has insufficient reserve travel and a non-conforming number plate round out the top three. Average tested mileage sits at 5,316, 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.
