PIAGGIO GTS300
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 GTS300's first-time pass rate has risen 3.3 points since 2012, 86.4% to 89.7%.
Pass rate by mileage
A low-mileage GTS300 passes first time 91.5% of the time; by 40k that's 78.0%.
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 GTS300 beats 3 of its 4 closest rivals (PIAGGIO PX 200 E, PIAGGIO X9, LAMBRETTA GP200).
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 GTS300.

Pass rate by registration year
Best year to buy used: 2012 (91.2% pass). Weakest: 2009 (87.6%).
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.
PIAGGIO GTS300 FAQ
