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 FIREFOX beats 1 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO ZIP, PIAGGIO NRG).

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 FIREFOX.

Pass rate by registration year

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.

MALAGUTI FIREFOX FAQ

What is the best year of FIREFOX to buy used?

By first-time pass rate, 2006-registered examples do best (72.5%) and 1997 worst (56.4%). Condition and history still trump the year.

How many miles will a FIREFOX last?

The median FIREFOX shows 7,492 miles at test, and examples around 30k miles still pass 68.0% of the time — mileage alone rarely kills one.
