1972 Honda CB450K · Sprockets Buying guide

Keep sprocket size and retaining hardware requirements separate

The 15-tooth sprocket references 23801-348-690 and asks buyers to count teeth and check chain length. The plate instead references 23811-292-000 and includes two 92101-06016-0A bolts, without the sprocket itself.

Check the drive arrangement rather than assigning an original ratio

The listing establishes this product’s 15-tooth count, not the original gearing of every motorcycle or its current modifications. Count the installed teeth and check chain length as requested. Confirm the fitted drive requirements separately before assuming a change preserves chain compatibility or produces a particular gearing result.

Add retaining hardware from the component actually needed

The plate set supplies a plate and two bolts with separately stated Honda references. Compare the removed retaining parts and any requirements of the sprocket selected. Buying that set does not supply the sprocket or drive chain, and an individual sprocket purchase does not confirm new plate hardware included.

Buying questions

Does the 15-tooth label establish the motorcycle’s factory tooth count?

It describes the offered sprocket, not proof of the motorcycle’s original gearing. The listing asks you to count the fitted teeth and check chain length. Use those checks with the actual drive arrangement instead of assigning a factory specification from the product name.

Can the plate set be treated as a sprocket installation package?

Its confirmed contents are the retaining plate and two bolts. The sprocket and final-drive chain are separate requirements. Compare the exact fastening arrangement and any additional components needed before treating those three supplied pieces as the whole installation order.

Does tooth count alone verify the chain already fitted?

The description explicitly asks for a chain-length check alongside counting sprocket teeth. It does not supply every chain or altered-drive specification. Identify the fitted chain arrangement and required compatibility before selecting the replacement from tooth count alone.
