How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the SENDA (RESTRICTED) beats 0 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO ZIP, PIAGGIO NRG).

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 SENDA (RESTRICTED).

Pass rate by registration year

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

Best year to buy used: 2001 (53.2% pass). Weakest: 2000 (40.5%).
