How to Replace Kawasaki KLX110 Chain and Sprockets

The chain and sprockets on dirt bikes like the Kawasaki KLX110 wear out much faster than those on road bikes.

When it’s time to change out these two Kawasaki motorcycle parts, watch our KLX110 chain and sprocket replacement video above and follow the steps below to get this job done.

Tools and Parts Needed – Kawasaki KLX Chain & Sprocket Replacement


  • Ratchet and extension
  • 8mm, 14mm, 22mm sockets
  • 10mm, 14mm wrenches
  • Circlip pliers
  • Flathead screwdriver
  • Torque wrench
  • Chain tool 

NOTE: The chain and sprockets on a motorcycle should be replaced together as a set because old sprockets will quickly tear up a new chain, and an old chain will cause excessive wear to new sprockets.

Installing a Chain - Kawasaki KLX110

PRO TIP: Cutting the new chain too short will result in you having to buy another chain. The golden rule is to measure twice, and cut once.

Step 2. Use a chain tool to press out the chain pin at the point you want to break the new chain.

PRO TIP: If you don’t have a chain tool, you can use an angle grinder to grind away the flared head of the chain pin and then pry off the outer plate.

Step 3. Install the new chain over the new sprockets, then put the outer plate onto the master link and install the clip that secures the outer plate.

PRO TIP: Make sure the gap in the clip is facing away from the direction the chain rotates. This reduces the chances of something snagging the clip and pulling it off.

The next step is to clean and adjust the chain. Watch our Kawasaki KLX110 chain adjustment video above to see how to get that done.
