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 ES250/2.

Pass rate by registration year

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

Best year to buy used: 1971 (96.7% pass). Weakest: 1971 (96.7%).

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.
