Pass rate by mileage

how the CHALY's first-time pass rate falls with the odometer · class average 73.4%

A low-mileage CHALY passes first time 81.1% of the time; by 20k that's 78.5%.

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 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

answers computed from the data above · terms in the glossary

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.
