How rivals compare
On first-time pass rate the GL 1800 C beats 4 of its 4 closest rivals (SUZUKI GSX1400, SUZUKI GSX1300R, YAMAHA FJR1300A).
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 GL 1800 C.
Pass rate by registration year
Best year to buy used: 2013 (96.4% pass). Weakest: 2012 (94.3%).
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.
