How rivals compare
On first-time pass rate the GS1150 beats 3 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 GS1150.
Pass rate by registration year
Best year to buy used: 2001 (90.2% pass). Weakest: 2002 (85.9%).
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.
