1971 Honda CB500K · Sprockets Buying guide

Match the sprocket and retaining hardware

The sprocket listing specifies 17 teeth and a 530 chain application. The separate lock-plate package supplies the plate and two bolts. Neither listing describes a complete front-and-rear sprocket set or a new drive chain.

Do not choose gearing from the title alone

The offered front sprocket has 17 teeth and a 530 chain application. Compare both details with the motorcycle, including the existing rear sprocket and chain length if gearing has been changed. This guide does not assume every surviving CB500K still has its original setup.

The plate package is a separate order

The lock-plate listing names a plate and two bolts, while the sprocket listing describes the sprocket itself. Check the condition and arrangement of the installed retaining hardware. If you need the plate package, add it deliberately rather than assuming it comes with the sprocket.

Questions about sprockets

How do I check this sprocket against a converted chain drive?

The offered front sprocket is for 530 chain. Its product information requires a matching 530 rear sprocket and says 530 and 630 components cannot be mixed. Check the existing chain and rear sprocket before ordering for a converted motorcycle.

What should I compare before choosing the offered 17-tooth sprocket?

Count the teeth on the fitted front sprocket and check chain length. This listing supplies a 17-tooth steel sprocket, so compare that specification with the intended setup rather than assuming every previous owner retained the original gearing.

Should I replace the lock plate when ordering a new front sprocket?

Inspect the plate for bending, cracks, worn bolt holes or failure to lock securely. The separate replacement package provides one plate and two bolts for one front sprocket; choose it when the retained hardware needs renewal.

Not sure which part you need?
