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 DR400 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 DR400.

Pass rate by registration year

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

Best year to buy used: 2005 (84.6% pass). Weakest: 2000 (71.2%).

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.

SUZUKI DR400 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI DR400 reliable?

The SUZUKI DR400 is less reliable than average for its class: 79.1% of its 1,141 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3751 of 5426 models.

What does a DR400 fail its MOT on most?

lighting and signalling — 41% of all defects recorded against failed DR400 tests.

What is the best year of DR400 to buy used?

By first-time pass rate, 2005-registered examples do best (84.6%) and 2000 worst (71.2%). Condition and history still trump the year.

How many miles will a DR400 last?

The median DR400 shows 7,104 miles at test, and examples around 30k miles still pass 78.6% of the time — mileage alone rarely kills one.
