1978 Honda CB750K Drive Sprockets & Hardware

Check the drivetrain fitted to your 1978 Honda CB750K before choosing sprockets. The listed replacements are a 15-tooth front and a 41-tooth rear for a 630-chain setup. Count the installed teeth and compare chain details because previous changes may alter the required parts.

1978 Honda CB750K · Sprockets Buying guide

Compare the installed chain and both sprockets

The front and rear listings identify tooth counts and chain application. Mounting studs, nuts and lock washers are additional choices, so check both compatibility and package contents before ordering.

Verify gearing on the motorcycle

The two sprocket listings both ask buyers to count teeth and check chain length. Compare the actual fitted chain and sprockets, particularly if the motorcycle has undergone a conversion or previous gearing change. The model label alone does not identify the current drivetrain configuration.

Account for mounting pieces separately

The rear stud-and-nut package lists four of each component. The tongued lock washers are supplied in a separate two-pack. Read those contents against the hardware being replaced, and do not assume either sprocket purchase includes every fastener used at its mounting location.

Common questions

Which tooth counts are listed for this route?

The featured front sprocket has 15 teeth and the rear has 41, with both descriptions stating a 630-chain application for the 1977–78 CB750K. Compare the fitted drivetrain and chain length before choosing those replacements.

Will these suit a different chain conversion?

Their descriptions specifically name a 630-chain setup. If the fitted bike uses a different arrangement, compare the conversion components and intended sprockets rather than relying on the motorcycle year. Confirm the application when any part of the setup is unknown.

Does the rear hardware set include lock washers?

The rear stud-and-nut set lists four stud bolts and four nuts. The tongued lock washers are a separate two-pack. Compare both package descriptions with the mounting hardware required for the repair before adding individual components.
