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 MILER beats 0 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 MILER.

Pass rate by registration year

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

Best year to buy used: 2009 (79.7% pass). Weakest: 2007 (70.6%).

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.

KYMCO MILER FAQ

answers computed from the data above · terms in the glossary

Is the KYMCO MILER reliable?

The KYMCO MILER is about average for its class: 75.2% of its 1,396 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4274 of 5426 models.

What does a MILER fail its MOT on most?

brakes — 38% of all defects recorded against failed MILER tests.

What is the best year of MILER to buy used?

By first-time pass rate, 2009-registered examples do best (79.7%) and 2007 worst (70.6%). Condition and history still trump the year.

How many miles will a MILER last?

The median MILER shows 16,248 miles at test, and examples around 50k miles still pass 58.1% of the time — mileage alone rarely kills one.
