Zx 1000 Wjf: a strong MOT record by UK norms
Across 984 MOT tests, the Zx 1000 Wjf returns 93.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is lamp emitted colour, position. Rear registration plate lamp does not illuminate simultaneously and brake pads worn below 1.0 mm round out the top three. Average tested mileage sits at 11,288, 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.
