Data as of: DVSA MOT results to 2025
HARLEY-DAVIDSON 1200 SPORTSTER
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 1200 SPORTSTER's first-time pass rate has held steady since 2006 (72.5% → 73.3%).
Pass rate by mileage
A low-mileage 1200 SPORTSTER passes first time 80.2% of the time; by 20k that's 74.2%.
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.
