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
On first-time pass rate the C50 beats 4 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 C50.
Pass rate by registration year
Best year to buy used: 2005 (93.2% pass). Weakest: 1978 (74.4%).
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.
HONDA C50 FAQ
Is the HONDA C50 reliable?
The HONDA C50 is more reliable than average for its class: 81.7% of its 6,237 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #3242 of 5426 models.
What does a C50 fail its MOT on most?
lighting and signalling — 37% of all defects recorded against failed C50 tests.
What is the best year of C50 to buy used?
By first-time pass rate, 2005-registered examples do best (93.2%) and 1978 worst (74.4%). Condition and history still trump the year.
How many miles will a C50 last?
The median C50 shows 11,256 miles at test, and examples around 50k miles still pass 79.6% of the time — mileage alone rarely kills one.
