For Triumph motorcycle owners who wish to maintain their bikes themselves, changing the drive sprocket and chain can be a surprisingly straightforward task. No need to drag your bike to a dealer service department; this guide walks through the process with the necessary tools, materials, and steps to ensure a successful do-it-yourself (DIY) job.

Tools and Materials Needed

Tools

Socket set including a torque wrench Screwdrivers Pliers Chain breaker and riveter (if using a non-master link chain) Adjustable wrench Motorcycle stand for stability

Materials

New drive chain New front and/or rear sprockets Chain lubricant Cleaning solvent for cleaning parts

Steps to Change the Drive Sprocket and Chain

Step 1: Safety First

Ensure the motorcycle is on a stable stand to prevent it from tipping over. Disconnect the battery to avoid any electrical issues.

Step 2: Remove the Old Chain

For master link chains, remove the chain using pliers or a chain tool. For non-master link chains, use a chain breaker to remove the chain. Slide the chain off the sprockets.

Step 3: Remove the Rear Wheel (if necessary)

Loosen the axle nut and any other components securing the rear wheel. Slide the wheel out of the swingarm.

Step 4: Remove the Old Sprocket

Unscrew the bolts holding the rear sprocket and then remove it. For the front sprocket, remove the cover if applicable, then unscrew the front sprocket bolt and take off the sprocket.

Step 5: Install the New Sprocket

Place the new sprockets in position and tighten the bolts to the manufacturer’s specifications. Refer to your owner’s manual for torque settings.

Step 6: Install the New Chain

For a master link chain, loop it around the sprockets and connect the master link. For a non-master link chain, thread the chain through the rear sprocket and around the front sprocket. Use the chain breaker to connect the ends.

Step 7: Adjust Chain Tension

Adjust the chain tension according to the specifications in your owner’s manual. This typically involves adjusting the rear wheel position.

Step 8: Reinstall Rear Wheel

If you removed the rear wheel, reinstall it ensuring everything is aligned properly.

Step 9: Final Checks

Double-check all bolts and connections. Reconnect the battery and lubricate the chain.

Step 10: Test Ride

Take a short test ride to ensure everything is functioning properly. Listen for any unusual noises and check for proper chain tension.
