How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the ETZ beats 4 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).

YAMAHA YP250 82.5% pass · 12.4k tests YAMAHA WR250F 78.0% pass · 10.5k tests HONDA XR250 78.8% pass · 9,277 tests HONDA CBF250 84.9% pass · 7,536 tests

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 ETZ.

Pass rate by registration year

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

Best year to buy used: 1990 (94.0% pass). Weakest: 1989 (83.3%).

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.
