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 A-6.

Pass rate by registration year

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

Best year to buy used: 2008 (94.5% pass). Weakest: 2006 (90.2%).
