How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the ET4 beats 0 of its 4 closest rivals (PIAGGIO VESPA, HONDA PCX 125, HONDA Vision 110).

PIAGGIO VESPA 80.7% pass · 287k tests HONDA PCX 125 81.1% pass · 88.6k tests HONDA Vision 110 78.2% pass · 50.6k tests YAMAHA NMAX 125 82.2% pass · 33.8k 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 ET4.

Pass rate by registration year

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

Best year to buy used: 2003 (81.2% pass). Weakest: 2001 (66.7%).

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.
