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 T5 beats 3 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 T5.

Pass rate by registration year

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

Best year to buy used: 2003 (88.2% pass). Weakest: 1989 (73.2%).

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 T5 FAQ

answers computed from the data above · terms in the glossary

Is the PIAGGIO T5 reliable?

The PIAGGIO T5 is more reliable than average for its class: 81.2% of its 21,902 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #3334 of 5426 models.

What does a T5 fail its MOT on most?

lighting and signalling — 38% of all defects recorded against failed T5 tests.

What is the best year of T5 to buy used?

By first-time pass rate, 2003-registered examples do best (88.2%) and 1989 worst (73.2%). Condition and history still trump the year.

How many miles will a T5 last?

The median T5 shows 11,686 miles at test, and examples around 50k miles still pass 79.8% of the time — mileage alone rarely kills one.
