vs expected · age & mileage

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 by mileage

how the DNEPR's first-time pass rate falls with the odometer · class average 84.9%

A low-mileage DNEPR passes first time 84.9% of the time; by 30k that's 81.3%.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 1991 (86.8% pass). Weakest: 1993 (82.7%).

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.
