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 GT250 beats 4 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).

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 GT250.

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 GT250 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI GT250 reliable?

The SUZUKI GT250 is about average for its class: 85.1% of its 2,956 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2467 of 5426 models.

What does a GT250 fail its MOT on most?

lighting and signalling — 31% of all defects recorded against failed GT250 tests.

What is the best year of GT250 to buy used?

By first-time pass rate, 1982-registered examples do best (91.1%) and 1981 worst (78.4%). Condition and history still trump the year.

How many miles will a GT250 last?

The median GT250 shows 19,296 miles at test, and examples around 40k miles still pass 83.3% of the time — mileage alone rarely kills one.
