The pass rate is the MOT first-time pass: a roadworthiness check of the items an MOT covers (brakes, lights, tyres, steering, structure, emissions), not a full mechanical inspection of engine or gearbox internals. It is a reliability signal, not a complete measure of mechanical reliability. What this measures.
“vs expected” adjusts for age, mileage and test class, so a cherished classic and a hard-used commuter are compared fairly. How this works.
Pass rate over time
The TCM's first-time pass rate has fallen 8.5 points since 2022, 85.1% to 76.6%.

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
On first-time pass rate the TCM beats 1 of its 4 closest rivals (BMW R1200, KAWASAKI ZX-6R, BMW R1150).
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 TCM.

Pass rate by registration year
Best year to buy used: 2020 (82.1% pass). Weakest: 2022 (74.8%).
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.
VMOTO TCM FAQ
Is the VMOTO TCM reliable?
The VMOTO TCM is more reliable than average for its class: 78.1% of its 621 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #3895 of 5428 models.
What does a TCM fail its MOT on most?
lamps and reflectors — 36% of all defects recorded against failed TCM tests.
What is the best year of TCM to buy used?
By first-time pass rate, 2020-registered examples do best (82.1%) and 2022 worst (74.8%). Condition and history still trump the year.
