How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the UH 125 K6 beats 3 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

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 UH 125 K6.

Pass rate by registration year

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

Best year to buy used: 2006 (72.9% pass). Weakest: 2007 (71.9%).
