1975 Honda CB550K · Front Sprocket Buying guide

Choosing the front sprocket

Compare the fitted sprocket and retention hardware before ordering. This section offers a 17-tooth front sprocket and a separate lock-plate set. Record the existing tooth count, chain specification and part condition when planning the wider drivetrain work.

Confirm gearing first

Before buying, the sprocket description asks you to verify the number of teeth and the length of your chain. This one is the factory 17-tooth size for 530 pitch, and its fitment takes in 1974-78 CB550K bikes along with the CB500K and CB550F.

Inspect the retention hardware

The lock-plate listing recommends replacement when installing a new front sprocket. Its set includes the plate and two bolts, with a separate Honda reference for each. Compare the removed plate and bolts with the listed hardware instead of treating every retaining arrangement as interchangeable.

Sprocket FAQs

What chain size does the sprocket use?

This steel front sprocket listing specifies 17 teeth and 530 chain, with Honda reference 23801-300-010. It names the 1974-78 CB550K and asks customers to check existing teeth and chain length before ordering, especially on a modified drivetrain.

Does the lock plate set include bolts?

Yes. The plate comes with both bolts, matching Honda 23811-292-000 for the plate itself. Fitment covers 1974-78 CB550K bikes and a long list of other classic Honda models.

Is a rear sprocket listed for this bike?

The verified category currently lists the front sprocket and its retaining plate, rather than a rear sprocket or chain. Compare the fitted drive components and ask the store about matching rear and chain options for the planned repair.
