How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the T250 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 T250.

Pass rate by registration year

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

Best year to buy used: 1972 (92.9% pass). Weakest: 1971 (90.7%).
