CB450K parts by year and K designation
The catalog uses CB450K0 for 1965, 1966 and 1967, followed by K1 through K7 for 1968–1974. Keep the year with the K0 designation, since that code leads to three separate year pages here.
1965 CB450K0 · 1966 CB450K0 · 1967 CB450K0 · 1968 CB450K1 · 1969 CB450K2 · 1970 CB450K3 · 1971 CB450K4 · 1972 CB450K5 · 1973 CB450K6 · 1974 CB450K7
The 1980s CB450SC Nighthawk and 1982 CB450TC are separate family entries, while CL450K has its own range. None of those names should be shortened to CB450K when checking the listed fitment of a replacement.
Verify the listed application
Use the product’s stated model and year coverage to check a part. Where available, compare its reference number and measurements with your parts information and installed component. If the listing gives only a K code across several years, resolve any missing year coverage before ordering.
