Upgrade or restore your classic Honda motorcycle with this Genuine Honda Cam Chain Tensioner Damper — precision‑engineered and made in Japan. This authentic OEM...
Inspect the whole cam-drive assembly before ordering
The chain, damper and sprocket fasteners are distinct items. Their presence in one category does not make a complete timing-service kit or establish that every component needs replacement.
The featured replacement is specified as a 412 × 112-link silent cam chain. Before choosing a separately sold rivet link, obtain a verified joining match from the chain supplier. Confirm the exact chain and connector together before planning a split-chain installation.
Keep the fasteners and damper distinct
The bolt set contains two cam-sprocket flange knock bolts. The genuine Honda damper is a separate tensioner component. Use the service manual to inspect the mechanism and establish timing and assembly procedures before replacing parts.
Buying questions
Which parts need inspection beyond the cam chain?
Inspect the chain, guide, tensioner mechanism, damper and associated hardware as a system, and order the parts the inspection identifies. A new chain alone does not establish that the surrounding tensioning components are serviceable.
Does the chain include the tensioner damper?
The chain and genuine Honda tensioner damper are separate products. Build the order from the components your inspection identifies rather than assuming the chain is a complete kit.
Can I add any silent-chain rivet link?
Match the joining link to the exact chain specification and supplier instructions. Confirm compatibility of the separately listed link with the featured chain before buying it or planning a riveted installation.
