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 AP50 beats 2 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 AP50.

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.

SUZUKI AP50 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI AP50 reliable?

The SUZUKI AP50 is less reliable than average for its class: 66.7% of its 8,863 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4923 of 5426 models.

What does a AP50 fail its MOT on most?

lighting and signalling — 34% of all defects recorded against failed AP50 tests.

What is the best year of AP50 to buy used?

By first-time pass rate, 1977-registered examples do best (84.4%) and 1998 worst (63.9%). Condition and history still trump the year.

How many miles will a AP50 last?

The median AP50 shows 7,823 miles at test, and examples around 30k miles still pass 74.5% of the time — mileage alone rarely kills one.
