Yzf-R1: a strong MOT record by UK norms

Across 729 MOT tests, the Yzf-R1 returns 89.4% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-conforming number plate. Direction indicator lamp missing and a missing rear reflector round out the top three. Average tested mileage sits at 26,756, 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 R1?

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.
