The picture

R Ninet: a strong MOT record by UK norms

Across 3,196 MOT tests, the R Ninet returns 92.5% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-conforming number plate. Tyre tread under the limit and a missing rear reflector round out the top three. Average tested mileage sits at 7,133, 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.

Year-band analysis

Best year to buy. Worst to avoid.

First-time MOT pass rate split by registration band. A 1.6-point gap between bands is modest — the year you buy BMW R Ninet makes a small but real difference to MOT outcomes.

Best band to buy

93.3%

2018–2020 registration

the 2018–2020 band climbs to 93.3% — a 1.6-point improvement. Failures here are mostly wear items: indicates excessive fluctuation of brake effort, missing — the structural issues that drag down older examples don't appear in the top-10 for this band. The stricter post-2018 MOT test rules meant manufacturers had to tighten up emissions and electrical checks, but this band still shows far fewer major failures on suspension and bodywork than the older fleet.

Band to be cautious about

91.7%

Pre-2018 registration

On the older band (pre-2018), the data shows a 91.7% pass rate against a fleet average of 93.3% on the newer band. The main culprits logged at test: tread depth is below minimum requirements of 1.0mm, indicates excessive fluctuation of brake effort, and does not conform to the specified requirements. Average mileage on test for this band is 9,261 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2018-2020 (93.3% first-time pass). Worst band to avoid: pre-2018 (91.7% pass). That's a 1.6-point spread across 3,003 older tests and 1,620 newer ones — year of build makes a material difference on this model.

Buying or keeping a R Ninet?

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 R Ninet 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.
