Pass rate over time
The CD's first-time pass rate has fallen 2.0 points since 2006, 82.0% to 80.0%.
Pass rate by mileage
A low-mileage CD passes first time 86.7% of the time; by 40k that's 86.8%.
First-time pass rate by odometer reading at test, 10,000-mile bands for this model. Mileage is the strongest reliability signal. See the full curve.

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 CD beats 4 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).
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 CD.
Pass rate by registration year
Best year to buy used: 1971 (90.2% pass). Weakest: 1981 (83.0%).
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 CD FAQ
Is the HONDA CD reliable?
The HONDA CD is more reliable than average for its class: 85.7% of its 725 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #2306 of 5426 models.
What does a CD fail its MOT on most?
lighting and signalling — 34% of all defects recorded against failed CD tests.
What is the best year of CD to buy used?
By first-time pass rate, 1971-registered examples do best (90.2%) and 1981 worst (83.0%). Condition and history still trump the year.
How many miles will a CD last?
The median CD shows 22,830 miles at test, and examples around 40k miles still pass 86.8% of the time — mileage alone rarely kills one.
