SYM FIDDLE II 125
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 FIDDLE II 125's first-time pass rate has fallen 11.6 points since 2013, 74.1% to 62.5%.
Pass rate by mileage
A low-mileage FIDDLE II 125 passes first time 87.9% of the time; by 20k that's 71.6%.
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.

Pass rate by registration year
Best year to buy used: 2010 (82.0% pass). Weakest: 2011 (73.0%).
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.
