Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.
How rivals compare
On first-time pass rate the ZIP beats 3 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO NRG, PEUGEOT VIVACITY).
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 ZIP.
Pass rate by registration year
Best year to buy used: 2020 (86.8% pass). Weakest: 2010 (69.1%).
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.
PIAGGIO ZIP FAQ

What does a ZIP fail its MOT on most?
lighting and signalling — 34% of all defects recorded against failed ZIP tests.
What is the best year of ZIP to buy used?
By first-time pass rate, 2020-registered examples do best (86.8%) and 2010 worst (69.1%). Condition and history still trump the year.
How many miles will a ZIP last?
The median ZIP shows 8,882 miles at test, and examples around 50k miles still pass 67.1% of the time — mileage alone rarely kills one.
