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.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the RGA beats 2 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).

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 RGA.

Pass rate by registration year

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

Best year to buy used: 1984 (88.5% pass). Weakest: 1984 (88.5%).

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.
