How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the WR 125 X beats 0 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 WR 125 X.

Pass rate by registration year

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