Pass rate over time
The GW's first-time pass rate has fallen 3.5 points since 2017, 89.7% to 86.2%.
Pass rate by mileage
A low-mileage GW passes first time 94.1% of the time; by 40k that's 91.9%.
First-time pass rate by odometer reading at test, 10,000-mile bands for this model. Mileage is the strongest reliability signal. See the full curve.

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 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
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
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.
