How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the EN 125 S 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 EN 125 S.

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

Best year to buy used: 2011 (79.3% pass). Weakest: 2006 (72.7%).
