Pass rate over time
The CHALY's first-time pass rate has risen 1.1 points since 2006, 73.1% to 74.2%.
Pass rate by mileage
A low-mileage CHALY passes first time 81.1% of the time; by 20k that's 78.5%.
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 CHALY beats 1 of its 1 closest rivals (HONDA C90).
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 CHALY.
Pass rate by registration year
Best year to buy used: 1984 (90.6% pass). Weakest: 1979 (75.8%).
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 CHALY FAQ
Is the HONDA CHALY reliable?
The HONDA CHALY is more reliable than average for its class: 81.5% of its 966 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #3270 of 5426 models.
What does a CHALY fail its MOT on most?
lighting and signalling — 57% of all defects recorded against failed CHALY tests.
What is the best year of CHALY to buy used?
By first-time pass rate, 1984-registered examples do best (90.6%) and 1979 worst (75.8%). Condition and history still trump the year.
How many miles will a CHALY last?
The median CHALY shows 8,782 miles at test, and examples around 20k miles still pass 78.5% of the time — mileage alone rarely kills one.
