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 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
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
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.
