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 HN beats 0 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

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 HN.

Pass rate by registration year

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

Best year to buy used: 2012 (69.5% pass). Weakest: 2016 (54.2%).

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.

HUONIAO HN FAQ

answers computed from the data above · terms in the glossary

Is the HUONIAO HN reliable?

The HUONIAO HN is less reliable than average for its class: 60.9% of its 937 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #5183 of 5426 models.

What does a HN fail its MOT on most?

lamps and reflectors — 32% of all defects recorded against failed HN tests.

What is the best year of HN to buy used?

By first-time pass rate, 2012-registered examples do best (69.5%) and 2016 worst (54.2%). Condition and history still trump the year.

How many miles will a HN last?

The median HN shows 6,162 miles at test, and examples around 20k miles still pass 54.3% of the time — mileage alone rarely kills one.
