How rivals compare
On first-time pass rate the SECTOR beats 0 of its 4 closest rivals (PIAGGIO VESPA, HONDA PCX 125, HONDA Vision 110).
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 SECTOR.
Pass rate by registration year
Best year to buy used: 2000 (72.9% pass). Weakest: 1999 (61.3%).
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.
