Pass rate by registration year
how each model-year cohort fares · registration year from first use date
Best year to buy used: 1964 (91.3% pass). Weakest: 1964 (91.3%).
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.
