Pass rate over time
The 404DS's first-time pass rate has risen 8.0 points since 2006, 82.9% to 90.9%.
Pass rate by mileage
A low-mileage 404DS passes first time 80.7% of the time; by 40k that's 58.8%.
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 404DS beats 2 of its 4 closest rivals (KAWASAKI ER5, SUZUKI GS500, SUZUKI AN400).
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 404DS.
Pass rate by registration year
Best year to buy used: 2009 (87.5% pass). Weakest: 2004 (76.7%).
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.
CCM 404DS FAQ
Is the CCM 404DS reliable?
The CCM 404DS is less reliable than average for its class: 78.2% of its 2,554 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3881 of 5426 models.
What does a 404DS fail its MOT on most?
lighting and signalling — 36% of all defects recorded against failed 404DS tests.
What is the best year of 404DS to buy used?
By first-time pass rate, 2009-registered examples do best (87.5%) and 2004 worst (76.7%). Condition and history still trump the year.
How many miles will a 404DS last?
The median 404DS shows 5,466 miles at test, and examples around 40k miles still pass 58.8% of the time — mileage alone rarely kills one.
