Zx 1000 Wkf: a strong MOT record by UK norms
Across 961 MOT tests, the Zx 1000 Wkf returns 92.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Uneven braking force and stiff steering bearings round out the top three. Average tested mileage sits at 8,636, 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.
