Sv 650 Al7: a strong MOT record by UK norms
Across 774 MOT tests, the Sv 650 Al7 returns 89.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A non-functioning shock absorber and transmission belt, chain round out the top three. Average tested mileage sits at 14,961, which is the lens to read those failure rankings through.
