CL450K years and model codes
The seven catalog entries run from CL450K0 (1967) through K5 (1972), followed by a 1974 entry labelled CL450K6. No 1973 entry is listed here. Treat this as the store’s year list, not a factory suffix sequence or worldwide production history.
1967 CL450K0 · 1968 CL450K1 · 1969 CL450K2 · 1970 CL450K3 · 1971 CL450K4 · 1972 CL450K5 · 1974 CL450K6
If your documented year or K designation differs from these labels, ask the parts team to resolve the model identity before choosing a part. Do not use the adjacent year or a CB450K page as an assumed substitute.
Keep CL450K and CB450K searches separate
For a listed CL450K, check the full prefix, year and part reference in the product’s fitment details. Mounting dimensions and connections can help identify the component on a repaired or modified motorcycle, but they do not replace explicit model coverage.
