Chain care in four steps: clean, dry, lube while warm, wipe off the excess (illustrative)

How Do You Clean and Lubricate a Motorcycle Chain?

An O-ring motorcycle chain is cleaned with an O-ring-safe chain cleaner and a cloth; then a short ride throws off the cleaner and water, and the chain is lubricated while warm with a lube suitable for O-ring chains…

How Often (in km) Should a Motorcycle Chain Be Lubricated?

How often a chain should be lubricated is determined first by your motorcycle's service manual; a common recommendation is to clean and lubricate the chain about every 800 km.

Types of chain lube: road spray, off-road spray and paste grease; O-ring compatibility is a must for all (illustrative)

Which Chain Lube Should You Use? Spray or Liquid Grease?

On a sealed (O-ring, X-ring, XW-ring) chain, use a motorcycle chain lube whose packaging says it is suitable for O-ring chains.

List of products to use and not to use for chain cleaning (illustrative)

Can Kerosene, Diesel, Gasoline or Thinner Be Used to Clean a Chain?

No.

Do Automatic Chain Oilers Work?

Yes, when set up correctly: an automatic oiler feeds the chain small, regular amounts of lube while riding, helping keep the chain both lubricated and cleaner.

Cleaning a rusted chain and steps to prevent rust (illustrative)

How to Prevent and Clean Motorcycle Chain Rust

The way to prevent chain rust is to dry and lubricate the chain after rain and washing and before long storage; the layer of lube keeps water and salt away from the steel surface.

A seized chain link that does not straighten out, and inspection steps (illustrative)

How Do You Fix a Stiff (Seized) Chain Link?

A stiff (seized) link is a link that does not straighten out after leaving the sprocket and stays kinked; it is usually caused by lack of lube, dirt, rust or over-riveting a newly fitted master link.

Measuring slack at the middle of the chain's lower run (illustrative)

How Much Slack Should a Motorcycle Chain Have?

The correct chain slack varies by motorcycle; it is given in the service manual or, on most models, on a label on the swingarm.

Axle adjustment marks on both sides of the swingarm and equal adjustment (illustrative)

How Do You Adjust a Motorcycle Chain? Axle and Alignment Adjustment

Chain adjustment means sliding the rear axle forward or back along the swingarm to bring the chain slack to the value in the manual.

Measuring 20 pitches on a chain with a ruler and the increase in stretch (illustrative)

What Is Chain Stretch, How Is It Measured and What Should You Do?

Chain stretch is not the metal stretching; it is the pitch of every link growing slightly because of wear between the pin and bushing.

A noisy chain and a list of possible causes (illustrative)

What Causes Motorcycle Chain Noise and How Do You Stop It?

Chain noise is usually caused by lack of lube, incorrect tension, worn sprockets or a stretched chain.

Wear on the chain slider on the swingarm and inspection steps (illustrative)

Why Are the Chain Slider and Chain Guard Important?

A chain slider is a plastic or rubber part at the front of the swingarm that the chain slides over; it keeps the chain from rubbing against the swingarm.

Approximate service life comparison of sealed and non-sealed chains (illustrative)

How Many Km Does a Motorcycle Chain Last? Average Life and RK Chain Durability

There is no single km figure for chain life; it is determined by maintenance, seal type, engine power and road conditions.

Replacing the kit of front sprocket, chain and rear sprocket together (illustrative)

When Should a Chain and Sprocket Kit Be Replaced? Do the Sprockets Need Replacing Too?

The chain, front sprocket and rear sprocket work together and wear together; that is why all three should be replaced together.

Comparison of a new sprocket and a sprocket worn into a hook shape (illustrative)

What Are Shark Fin Teeth? How Do You Recognize a Worn, Pointed Sprocket?

“Shark fin teeth” is the hook shape that forms on a worn sprocket when one face of the teeth is gouged out, the tips become pointed and lean in one direction.

Comparison of steel and aluminum rear sprockets by weight, service life, use and price

Aluminum or Steel Rear Sprocket?

A steel rear sprocket is the choice for everyday road use and long life; an aluminum rear sprocket is the choice for light weight and performance.

Examples of final drive ratio by front and rear sprocket tooth count

How Does Changing Sprocket Size Affect Speed and Torque?

Final drive ratio = rear sprocket tooth count ÷ front sprocket tooth count.

A broken chain and its possible consequences (illustrative)

What Damage Can a Broken Chain Do to the Motorcycle?

A chain that breaks while riding instantly cuts power to the rear wheel; if the chain wraps around the rear sprocket or the swingarm, the rear wheel can lock and the motorcycle can skid.

Chain selection and maintenance steps for off-road use (illustrative)

Chain Selection and Maintenance for Enduro and Off-Road

An O-ring chain is preferred for enduro and long off-road rides, while a light, low-friction non-sealed or thin O-ring racing chain is preferred for motocross racing.

Comparison of clip-type and rivet-type master links (illustrative)

Rivet or Clip-Type Master Link? When to Use Each

A master link (connecting link) is the link that joins the two ends of a chain; there are two types: clip-type and rivet-type.

The closed end of the master link clip should face the direction of chain travel (illustrative)

Which Way Should the Master Link Clip Face?

The closed (rounded) end of the clip should face the direction of chain travel, and the open end should face backward.

Chain riveting steps (illustrative)

How to Rivet a Chain: Step-by-Step Rivet-Type Master Link Installation

Riveting a chain means spreading the pin ends of a rivet-type master link with a chain tool so that the outer plate is fixed permanently.

Finding the link count by counting the pins on a chain (illustrative)

How to Calculate Chain Link Count: A Guide to Shortening a Chain

Your motorcycle's chain link count is listed in the owner's manual and in chain catalogs (for example the RK catalog); the safest method is to use that value.

Choho motorcycle chain and product groups (illustrative)
