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 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

how each model-year cohort fares · registration year from first use date

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

answers computed from the data above · terms in the glossary

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.
