How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the GSX beats 2 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).

BMW R1200 92.9% pass · 299k tests BMW R1150 88.5% pass · 171k tests TRIUMPH SPRINT 85.6% pass · 133k tests SUZUKI GSF1200 82.4% pass · 97.6k tests

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 GSX.

Pass rate by registration year

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

Best year to buy used: 2016 (93.4% pass). Weakest: 1990 (71.3%).

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.
