Pass rate by mileage

how the ARN's first-time pass rate falls with the odometer · class average 73.4%

A low-mileage ARN passes first time 70.2% of the time; by 20k that's 56.8%.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the ARN beats 0 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

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 ARN.

Pass rate by registration year

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

Best year to buy used: 2007 (56.9% pass). Weakest: 2007 (56.9%).

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.
