1981 Honda CB750K · Sprockets Buying guide

Confirm both sprockets and the installed chain

The front and rear listings each identify tooth count, chain type and a replacement reference. Read them together with the installed parts; neither listing determines the chain length your motorcycle currently needs.

Treat the two specifications as separate checks

The available front option is 18 teeth; the rear option is 46. Both are described for 530 chain. Count the parts actually installed, rather than assuming a previous owner kept those specifications. Record any difference before choosing a replacement or requesting help with the combination.

Review the chain before changing a tooth count

The sprocket descriptions ask customers to check tooth count and chain length. Neither product supplies a chain-length decision for a modified motorcycle. If you are changing the gearing, provide the current chain and both sprocket specifications so the proposed combination can be reviewed.

Common questions

What sprocket sizes are listed here?

The current front listing is an 18-tooth steel sprocket for 530 chain. The rear listing is a 46-tooth steel sprocket, also for 530 chain. Compare those product specifications with the installed parts before selecting them.

Does buying these sprockets tell me the chain length?

No chain length is specified by these two product choices. Their descriptions tell you to check tooth count and chain length. Use the installed setup and any planned changes when identifying a chain requirement; do not infer it from the year alone.

What should I check on a motorcycle with a changed rear wheel?

Compare the installed rear sprocket’s mounting details, tooth count and chain designation with the listed part. A model-year fitment entry does not describe a custom wheel. Provide clear photographs and the wheel details before assuming the replacement is suitable.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
