How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the GS250T beats 3 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 GS250T.

Pass rate by registration year

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

Best year to buy used: 1981 (83.3% pass). Weakest: 1980 (82.9%).
