Pass rate by mileage

how the QM's first-time pass rate falls with the odometer · class average 84.9%

A low-mileage QM passes first time 80.1% of the time; by 20k that's 57.5%.

First-time pass rate by odometer reading at test, 10,000-mile bands for this model. Mileage is the strongest reliability signal. See the full curve.

Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the QM beats 0 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).

YAMAHA YP250 82.5% pass · 12.4k tests YAMAHA WR250F 78.0% pass · 10.5k tests HONDA XR250 78.8% pass · 9,277 tests HONDA CBF250 84.9% pass · 7,536 tests

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the QM.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2015 (79.6% pass). Weakest: 2017 (73.6%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

SINNIS QM FAQ

answers computed from the data above · terms in the glossary

Is the SINNIS QM reliable?

The SINNIS QM is less reliable than average for its class: 76.4% of its 1,016 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #4134 of 5426 models.

What does a QM fail its MOT on most?

lamps and reflectors — 41% of all defects recorded against failed QM tests.

What is the best year of QM to buy used?

By first-time pass rate, 2015-registered examples do best (79.6%) and 2017 worst (73.6%). Condition and history still trump the year.

How many miles will a QM last?

The median QM shows 4,942 miles at test, and examples around 20k miles still pass 57.5% of the time — mileage alone rarely kills one.
