The picture

Unclassified: above-average pass rates, with caveats

Across 5,229 MOT tests, the Unclassified returns 85.0% first-time pass — above the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. A non-conforming number plate and a missing rear reflector round out the top three. Average tested mileage sits at 19,840, 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.

Top ten reasons for rejection.

Filter failures:

  1. 01

    A suspension pin, bush or joint excessively worn

    71 occurrences · 0.9% of tests

  2. 02

    A shock absorber not functioning or leaking severely

    57 occurrences · 0.7% of tests

  3. 03

    Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning

    47 occurrences · 0.6% of tests

  4. 04

    Reflector missing or reflecting white to the rear

    35 occurrences · 0.4% of tests

  5. 05

    Audible warning not working

    31 occurrences · 0.4% of tests

  6. 06

    Significant brake effort recorded with no brake applied indicating a binding brake

    24 occurrences · 0.3% of tests

  7. 07

    A lamp missing or inoperative

    24 occurrences · 0.3% of tests

  8. 08

    Tyre tread depth not in accordance with the requirements

    23 occurrences · 0.3% of tests

  9. 09

    Projected beam image is obviously incorrect

    23 occurrences · 0.3% of tests

Counts cover Major and Dangerous defects logged at test. Advisory items excluded so this shows why a car was rejected, not just what the tester flagged in passing.

Year-band analysis

Best year to buy. Worst to avoid.

First-time MOT pass rate split by registration band. A 10.6-point gap between bands means the year you buy Yamaha Unclassified has a real effect on what turns up at the garage.

Best band to buy

95.8%

2021+ registration

the 2021-on band climbs to 95.8% — a 10.6-point improvement. Tests in this band average 3,488 miles — roughly 17K miles fewer on the clock than the older band. Failures here are mostly wear items: inoperative, missing — 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

85.2%

Pre-2018 registration

On the older band (pre-2018), the data shows a 85.2% pass rate against a fleet average of 95.8% on the newer band. The main culprits logged at test: pin or bush excessively worn, has a serious fluid leak, and not working. Average mileage on test for this band is 20,334 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2021+ (95.8% first-time pass). Worst band to avoid: pre-2018 (85.2% pass). That's a 10.6-point spread across 7,483 older tests and 165 newer ones — year of build makes a material difference on this model.

Buying or keeping an Unclassified?

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 an Unclassified 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.
