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 GSF beats 1 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).

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 GSF.

Pass rate by registration year

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

Best year to buy used: 2011 (95.4% pass). Weakest: 1995 (66.5%).

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 GSF FAQ

What is the best year of GSF to buy used?

By first-time pass rate, 2011-registered examples do best (95.4%) and 1995 worst (66.5%). Condition and history still trump the year.

How many miles will a GSF last?

The median GSF shows 18,828 miles at test, and examples around 50k miles still pass 77.3% of the time — mileage alone rarely kills one.
