Sport Motorcycle Maintenance
Sport bikes run at high engine speeds. These are the parts to check regularly to keep performance at its best.

The chain carries power from the engine to the rear wheel. Because it runs in the open, it is the first part to collect dust, sand, and water spray. A dry, crusted chain makes the ride feel rough and noisy, and speeds up wear on both the front and rear sprockets.
When does a chain need cleaning?
As a general rule, clean and lubricate the chain every 500–1,000 km, or sooner after riding through rain and muddy roads. Other easy signs: the chain looks dry or rusty, it squeaks, or mud has built up between the links.
Cleaning steps
- Put the motorcycle on its center stand or a paddock stand so the rear wheel turns freely. Make sure the engine is off.
- Spray on chain cleaner, or use a small amount of kerosene. Avoid gasoline and harsh solvents on O-ring chains because they can damage the rubber seals.
- Scrub every side of the chain with a chain brush while turning the wheel by hand.
- Wipe it dry with a clean cloth, then let it sit for a few minutes.
- Spray chain lube evenly on the inner side of the chain and leave it for 10–15 minutes before riding.
Check the tension too
A chain that is too loose can jump off the sprocket, while one that is too tight loads the bearings and wears faster. Press the middle of the lower chain run: free play is usually around 2–3 cm, but follow the figure in your owner's manual.
When should it be replaced? If the sprocket teeth are pointed like shark fins, the chain can no longer be adjusted, or some links are seized, replace the chain and sprockets as a set so they wear evenly.
