How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the T20 beats 4 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).

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 T20.

Pass rate by registration year

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

Best year to buy used: 1967 (83.9% pass). Weakest: 1967 (83.9%).

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.
