Yzf1000: above-average pass rates, with caveats
Across 577 MOT tests, the Yzf1000 returns 84.9% first-time pass — above the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. Direction indicator lamp missing and tyre tread under the limit round out the top three. Average tested mileage sits at 29,893, 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.

Buying or keeping a Yzf1000?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Yzf1000 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
