About the Honda CB750
Choose the engine generation and complete model before planning a CB750 repair.
Honda introduced the CB750 Four in 1969 with a four-cylinder engine, four exhaust silencers and a front disc brake. The family later expanded into twin-cam Super Sports and Customs, the Hondamatic, Police versions and several Nighthawk generations.

Both K and F names cross the SOHC-to-DOHC change. The model comparison and original frame/engine reference chart below help identify the motorcycle. The repair table links actual gasket and carburetor choices, while the child guides handle their narrower model-year and chassis details.
Know your CB750 before choosing partsHonda CB750 model differences
Compare the K, F, A, C, L, P and Nighthawk families below. Use these model identities to choose a collection. Market specifications can differ; the child guides provide detailed repair applications.
1969–1978
CB750K · SOHC Four
The original K family uses a single overhead camshaft. Four separate exhaust silencers give an unmodified bike its familiar appearance. K0 through K8 identify successive versions; they are not one universal parts application.

CB750F · SOHC Super Sport
The early Super Sport is still a SOHC four. Later SOHC sport versions gained ComStar wheels and twin front discs alongside a rear disc, making wheel and brake identification especially useful when comparing them with a K.

CB750K · DOHC Four
The redesigned K moves to a 16-valve, twin-cam engine, CV carburetors and transistor ignition. It retains the traditional four-silencer appearance, so exhaust styling alone cannot distinguish it from a SOHC K.

CB750F · DOHC Super Sport
The later F combines a 748cc, 16-valve DOHC engine with a four-into-two exhaust and two front brake discs plus one rear disc. It is a different engine generation from the 1975–1978 F.

CB750A · Hondamatic
The 736cc SOHC Hondamatic uses a torque converter and two forward ranges selected by the rider’s left foot. Its transmission and wet-sump lubrication distinguish it from the conventional five-speed SOHC models.

CB750C · Custom
The Custom takes the DOHC four in a more relaxed direction, with taller handlebars and a lower, stepped seat. Those changes make control layout, cable routing and chassis details relevant when comparing it with a K or F.

CB750L · Limited Edition
Listed as CB750L in the identification chart, this is the CB750K Limited Edition celebrating a decade of the 750 Four. It belongs to the redesigned DOHC family; its anniversary identity does not make it an early SOHC K.

CB750P · Police
The P identifies a police version. Police versions can carry dedicated patrol equipment, including warning lights and protective bars. A civilian-looking restoration may therefore still have police-specific fittings underneath.

CB750SC & Nighthawk 750
Early CB750SC
Honda’s 1982 SC has chain drive, a TRAC front fork and specified valve-clearance adjustment. Its suspension and brake details deserve their own application check.
Later SC / Nighthawk S
The 1984 CB750SC uses a six-speed arrangement, including overdrive, and shaft final drive. Check the market designation too; CB700SC entries are not automatically CB750 applications.
Nighthawk 750 from 1991
The later 747cc DOHC four has hydraulic valve-clearance adjusters. It uses a front disc and rear drum, so neither the Nighthawk name nor engine capacity is enough to choose brake or engine parts.
What about the Seven Fifty? Honda’s CB750 introduced in 1992 was sold in Europe as the CB Seven Fifty. Its CBX750F-derived engine and 17-inch front and rear wheels distinguish it from the earlier K/F generations. Confirm the market model before using a Nighthawk or classic Super Sport application.
Not sure which CB750 you have?Honda CB750 VIN, frame & engine number chart
Compare your bike’s frame/VIN and engine markings with the reference entries below, then choose the complete model and year when shopping for Honda CB750 parts. Check the frame and engine separately, especially if the engine has been replaced.
How to use this chart: These are reference entries, not complete serial-number ranges. A matching prefix alone does not confirm the year or part fitment. Check each product’s application and the component actually fitted to your bike.
