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 DR350 beats 1 of its 4 closest rivals (SUZUKI AN400, SUZUKI DR-Z400S, YAMAHA RD350).

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 DR350.

Pass rate by registration year

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 DR350 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI DR350 reliable?

The SUZUKI DR350 is less reliable than average for its class: 79.6% of its 2,246 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3666 of 5426 models.

What does a DR350 fail its MOT on most?

lighting and signalling — 30% of all defects recorded against failed DR350 tests.

What is the best year of DR350 to buy used?

By first-time pass rate, 1997-registered examples do best (89.3%) and 1992 worst (70.8%). Condition and history still trump the year.

How many miles will a DR350 last?

The median DR350 shows 14,722 miles at test, and examples around 40k miles still pass 86.0% of the time — mileage alone rarely kills one.
