How rivals compare

same type, similar capacity, high test volume

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

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

Best year to buy used: 2013 (96.4% pass). Weakest: 2012 (94.3%).
