LEXMOTO DIABLO
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 DIABLO's first-time pass rate has risen 3.5 points since 2018, 69.2% to 72.7%.
Pass rate by mileage
A low-mileage DIABLO passes first time 75.2% of the time; by 20k that's 71.3%.
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 DIABLO 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 DIABLO.

Pass rate by registration year
Best year to buy used: 2017 (80.8% pass). Weakest: 2018 (69.3%).
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 DIABLO FAQ
Is the LEXMOTO DIABLO reliable?
The LEXMOTO DIABLO is about average for its class: 73.1% of its 2,123 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4490 of 5428 models.
What does a DIABLO fail its MOT on most?
lamps and reflectors — 33% of all defects recorded against failed DIABLO tests.
What is the best year of DIABLO to buy used?
By first-time pass rate, 2017-registered examples do best (80.8%) and 2018 worst (69.3%). Condition and history still trump the year.
How many miles will a DIABLO last?
The median DIABLO shows 7,716 miles at test, and examples around 20k miles still pass 71.3% of the time — mileage alone rarely kills one.
