The picture

Gpd125-A Nmax 125 Abs: above-average pass rates, with caveats

Across 5,689 MOT tests, the Gpd125-A Nmax 125 Abs returns 83.0% first-time pass — above the UK fleet average. The single most-logged Major fail is brake pads worn below 1.0 mm. Tyre tread under the limit and a non-functioning shock absorber round out the top three. Average tested mileage sits at 36,494, 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 1.9-point gap between bands is modest — the year you buy Yamaha Gpd125 A Nmax 125 Abs makes a small but real difference to MOT outcomes.

Best band to buy

80.7%

2021+ registration

the 2021-on band climbs to 80.7% — a 1.9-point improvement. Tests in this band average 31,395 miles — roughly 19K miles fewer on the clock than the older band. Failures here are mostly wear items: less than 1.0 mm thick, tread depth is below minimum requirements of 1.0mm — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.

Band to be cautious about

78.9%

Pre-2018 registration

On the older band (pre-2018), the data shows a 78.9% pass rate against a fleet average of 80.7% on the newer band. The main culprits logged at test: less than 1.0 mm thick, tread depth is below minimum requirements of 1.0mm, and has negligible damping effect. Average mileage on test for this band is 50,324 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2021+ (80.7% first-time pass). Worst band to avoid: pre-2018 (78.9% pass). That's a 1.9-point spread across 1,594 older tests and 5,525 newer ones — year of build makes a material difference on this model.

Buying or keeping a Gpd125 A Nmax 125 Abs?

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 Gpd125 A Nmax 125 Abs 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.
