Data as of: DVSA MOT results to 2025
SUZUKI UG110
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 UG110's first-time pass rate has fallen 6.9 points since 2006, 83.0% to 76.1%.
Pass rate by mileage
A low-mileage UG110 passes first time 78.0% of the time; by 20k that's 75.9%.
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 UG110 beats 3 of its 4 closest rivals (YAMAHA YBR 125, HONDA C90, HONDA CG125).
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 UG110.

Pass rate by registration year
Highest pass rate: 2000 (77.8%). Lowest: 2003 (68.3%). Every UG110 year compared →
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.
SUZUKI UG110 FAQ
Is the SUZUKI UG110 reliable?
The SUZUKI UG110 is more reliable than average for its class: 76.5% of its 890 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4125 of 5428 models.
What does a UG110 fail its MOT on most?
brakes: 32% of all defects recorded against failed UG110 tests.
What is the best year of UG110 to buy used?
By first-time pass rate, 2000-registered examples do best (77.8%) and 2003 worst (68.3%). Condition and history still trump the year.
How many miles will a UG110 last?
The median UG110 shows 8,034 miles at test, and examples around 20k miles still pass 75.9% of the time, so mileage alone rarely decides the result.
