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

same type, similar capacity, high test volume

On first-time pass rate the FLY 100 beats 0 of its 4 closest rivals (PIAGGIO VESPA, HONDA Vision 110, PIAGGIO PX 125 (VESPA)).

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 FLY 100.

Pass rate by registration year

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

Best year to buy used: 2007 (75.5% pass). Weakest: 2008 (65.6%).

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.

PIAGGIO FLY 100 FAQ

answers computed from the data above · terms in the glossary

Is the PIAGGIO FLY 100 reliable?

The PIAGGIO FLY 100 is less reliable than average for its class: 70.3% of its 1,174 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4704 of 5426 models.

What does a FLY 100 fail its MOT on most?

lighting and signalling — 32% of all defects recorded against failed FLY 100 tests.

What is the best year of FLY 100 to buy used?

By first-time pass rate, 2007-registered examples do best (75.5%) and 2008 worst (65.6%). Condition and history still trump the year.

How many miles will a FLY 100 last?

The median FLY 100 shows 10,219 miles at test, and examples around 30k miles still pass 62.2% of the time — mileage alone rarely kills one.
