How rivals compare

same type, similar capacity, high test volume

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

PEUGEOT SPEEDFIGHT 65.2% pass · 83.7k tests PIAGGIO ZIP 71.3% pass · 79.0k tests PIAGGIO NRG 65.5% pass · 40.5k tests PEUGEOT VIVACITY 70.4% pass · 29.7k tests

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 MIO.

Pass rate by registration year

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

Best year to buy used: 2007 (79.9% pass). Weakest: 2006 (69.6%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.
