Yzf R6: above-average pass rates, with caveats
Across 3,094 MOT tests, the Yzf R6 returns 84.2% first-time pass — above the UK fleet average. The single most-logged Major fail is a missing rear reflector. A non-conforming number plate and rate of flashing not between 60 round out the top three. Average tested mileage sits at 20,819, 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 Yzf R6?
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 Yzf R6 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.
