How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the CB 600 F-4 beats 3 of its 4 closest rivals (KAWASAKI ZX-6R, SUZUKI GSF600, YAMAHA FZS600).

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 CB 600 F-4.

Pass rate by registration year

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

Best year to buy used: 2005 (82.9% pass). Weakest: 2003 (78.7%).
