Pass rate by registration year

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

Best year to buy used: 2012 (82.7% pass). Weakest: 2006 (75.7%).

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.
