How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the CL450 beats 4 of its 4 closest rivals (KAWASAKI ER5, YAMAHA XV535, SUZUKI GS500).

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 CL450.

Pass rate by registration year

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

Best year to buy used: 1971 (87.1% pass). Weakest: 1972 (75.0%).
