Vespa Gts 300 Super: a strong MOT record by UK norms
Across 657 MOT tests, the Vespa Gts 300 Super returns 90.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Brake pads worn below 1.0 mm and tyre not fitted in accordance round out the top three. Average tested mileage sits at 16,828, 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.
