The picture
Gsx1400: a strong MOT record by UK norms
Across 2,562 MOT tests, the Gsx1400 returns 91.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. Rate of flashing not between 60 and uneven braking force round out the top three. Average tested mileage sits at 25,901, 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 Gsx1400?
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 Gsx1400 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.
