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 GW 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 GW.

Pass rate by registration year

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

Best year to buy used: 2016 (91.1% pass). Weakest: 2013 (85.5%).

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 GW FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI GW reliable?

The SUZUKI GW is more reliable than average for its class: 89.5% of its 3,766 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #1111 of 5426 models.

What does a GW fail its MOT on most?

brakes — 34% of all defects recorded against failed GW tests.

What is the best year of GW to buy used?

By first-time pass rate, 2016-registered examples do best (91.1%) and 2013 worst (85.5%). Condition and history still trump the year.

How many miles will a GW last?

The median GW shows 6,940 miles at test, and examples around 40k miles still pass 91.9% of the time — mileage alone rarely kills one.
