Chains

How to Choose Motorcycle Drive Chains

Motorcycle drive chains are part of the secondary drivetrain, transferring engine power to the rear wheel through the front and rear sprockets. Choose a chain based on the motorcycle’s specified requirements, especially chain pitch and width, along with the number of links needed for installation.

You should also distinguish between standard chains and sealed chains, such as O-Ring or X-Ring types. These seals help retain internal lubrication and may affect maintenance and chain life. Always confirm that the selected type matches the motorcycle manufacturer’s instructions and the intended use.

What to Check Before Buying a Chain

• Check the owner’s manual or the reference on the installed chain to verify the pitch, width, and length.
• Make sure the number of links allows the tension to be adjusted correctly with the rear wheel axle position.
• Inspect the front and rear sprockets for condition and compatibility. Replacing only the chain may not be appropriate if either sprocket is worn.
• Confirm the included or required connection type, whether a clip-style master link or a riveted link, and use the proper tool for installation.
• After installation, adjust slack according to the motorcycle’s instructions and apply a motorcycle-specific chain lubricant.

Regular maintenance should include cleaning, lubrication, and inspection for stiff links, corrosion, uneven wear, or slack that changes as the wheel turns. A correctly tensioned chain should not be excessively tight or too loose. If in doubt, have the complete drivetrain checked.
