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 FMX's first-time pass rate has risen 7.9 points since 2018, 66.3% to 74.2%.
Pass rate by mileage
A low-mileage FMX passes first time 66.6% of the time; by 20k that's 67.8%.
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
On first-time pass rate the FMX beats 0 of its 4 closest rivals (PIAGGIO VESPA, HONDA PCX 125, HONDA Vision 110).
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 FMX.

Pass rate by registration year
Best year to buy used: 2015 (64.2% pass). Weakest: 2016 (63.8%).
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.
LEXMOTO FMX FAQ
Is the LEXMOTO FMX reliable?
The LEXMOTO FMX is less reliable than average for its class: 63.9% of its 1,431 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #5066 of 5428 models.
What does a FMX fail its MOT on most?
lamps and reflectors — 39% of all defects recorded against failed FMX tests.
How many miles will a FMX last?
The median FMX shows 8,334 miles at test, and examples around 20k miles still pass 67.8% of the time — mileage alone rarely kills one.
