How to Fix Your Motorcycle Chain: A Complete Step-by-Step Guide

May 30, 2025

Your motorcycle's chain is a fundamental component that transmits power from the engine to the rear wheel. Proper maintenance ensures optimal performance, road safety, and prevents costly repairs. In this tutorial, we'll show you step-by-step how to fix your motorcycle chain, including realistic images to make your task easier.

Necessary materials

• Special chain grease or lubricant.

• Specific degreaser for chains.

• Special chain cleaning brush.

• Heavy duty work gloves.

• Fixed or socket wrench suitable for your motorcycle.

• Clean cloth.

• Chain repair kit (replacement links, clip or rivet, link tool).

Step 1: Thorough cleaning of the chain

It is crucial to start with a deep cleaning to identify any problems:

• Spray a specific degreaser on the entire chain.

• Let it sit for a few minutes to dissolve dirt and grease.

• Using a special brush, carefully scrub each link, making sure to remove all residue.

• Wipe the chain with a clean cloth until all traces of the degreaser are removed.

Step 2: Detailed visual inspection

Look carefully at the chain looking for:

• Twisted or deformed links.

• Obvious wear on pinion and crown teeth.

• Presence of rust.

• Rigid areas that do not flex correctly.

Mark problem spots with chalk or tape.

Step 3: Repair or replace links

Once the defective links have been identified during the inspection, it's time to act. This step is delicate, as an incorrect repair can compromise the entire motorcycle drivetrain. Below, we explain how to replace a link step by step:

1. Locate the defective link

• Slowly rotate the rear wheel until the damaged link is in a comfortable working position.

• Clean that section well with a rag to remove any dirt that could prevent you from seeing clearly.

2. Use a chain extractor or cutter

• Place the chain cutter tool over the link.

• Make sure the extractor pin is aligned with the rivet of the link you want to remove.

• Turn the tool screw firmly and slowly until the rivet begins to pop out.

• Remove the link once the rivet has been removed. If the tool is suitable, it will not damage the adjacent links.

3. Install the new link (master or connecting link)

• Insert the new master link. It can be clip-on (more common on low- and mid-displacement bikes) or riveted (more secure for powerful bikes and trail riding).

• If you use a clip:

  • Make sure it is inserted correctly: the closed side of the clip should face in the direction of chain rotation.

  • Use needle-nose pliers to install it precisely.

• If you use riveted link:

  • Use the riveting tool to expand the ends of the new pin.

  • Make sure not to over-tighten the pressure to avoid deforming the link.

4. Check the mobility of the new link

• Make sure the new link moves as freely as the others.

• If it is stiff or forced, remove and repeat the installation, as this could cause the chain to skip while driving.

5. Check alignment and safety

• Check that the clip is perfectly fitted (if it is a clip).

• Make sure there is no looseness or abnormal play.

• Spin the rear wheel a few times and observe how the chain behaves as it passes over the sprocket and crown.

Step 4: Precise tension adjustment

A chain that is too loose or too tight can cause damage:

• Slightly loosen the rear axle using the appropriate wrench.

• Use the rear tensioners to adjust the tension (refer to your motorcycle owner's manual for the exact recommended measurement).

• Check correct rear wheel alignment using reference marks.

• Retighten the rear axle to the torque specified by the manufacturer.

Step 5: Proper chain lubrication

Proper lubrication significantly extends chain life:

• Apply special lubricant evenly over the entire chain, focusing especially on the rollers and links.

• Perform this task when the chain is hot (after a short ride).

• Slowly rotate the rear wheel to ensure the lubricant penetrates each component well.

Additional tips for chain maintenance

• Regularly check chain tension and lubrication every 500-1000 kilometers or after riding on rough terrain.

• Always carry a basic repair kit with you on long rides.

• Always consult your motorcycle manual for specific procedures and additional recommendations.

Proper maintenance and repair of your motorcycle chain ensures safe, comfortable rides and prolongs the life of your motorcycle. Follow these steps and prepare for your next adventure with complete confidence.

Have a good trip and full throttle!
