Scrambler Desert Sled: a strong MOT record by UK norms
Across 494 MOT tests, the Scrambler Desert Sled returns 88.1% 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 stop lamp(s) does not illuminate by the operation of both brake controls round out the top three. Average tested mileage sits at 5,772, 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.
