About the Honda CB450
Carburetor, engine and chassis parts for three very different CB450 projects.
Honda introduced the DOHC CB450 in 1965 as a flagship developed primarily for the American market. The CB450 name later appeared on the Hawk and Nighthawk. For today’s restorer, the full model code is the starting point: the earlier K twin and the later T and SC models have different engine and chassis parts.
Choose your CB450 model
Use CB450K parts for the 1965–1974 DOHC twin, CB450T parts for the 1982 Hawk and CB450SC parts for Nighthawk listings. Individual products can have narrower year ranges, so keep the full code and year with each repair.
