Rear chain guide – precise OEM-style replacement for correct chain control

The replacement rear chain guide fully replaces the original guide positioned around the rear sprocket. Its purpose is to keep the drive chain on the correct path, stabilise its movement as it approaches the sprocket and limit unnecessary lateral movement.

The guide is manufactured from a durable plastic material selected for resistance to chain abrasion and mechanical impacts. Its precise application-specific OEM-style shape allows the correct version to install in the original position without drilling, cutting or other motorcycle modifications.

Whenever replacing the chain or complete chain-and-sprocket set, the condition of the chain guide should also be checked. It is a normal wear component, and excessive wear can affect the way a new chain runs through the final-drive system.

Correct chain guidance around the rear sprocket

The rear guide works in the area where the chain reaches the rear sprocket.

It helps maintain the intended chain position particularly during:

• hard acceleration,

• engine braking,

• jump landings,

• rapid rear suspension movement,

• deep ruts,

• rocky and rough terrain.

Under these conditions the chain can move considerably both vertically and laterally. The guide helps limit unwanted displacement and maintain stable engagement with the rear sprocket.

Precise OEM-style shape

Each guide is designed for a specific motorcycle application.

The correct version matches:

• original mounting points,

• swingarm geometry,

• rear-sprocket position,

• chain-path width,

• required chain position.

Installation therefore requires no:

• drilling,

• cutting,

• grinding,

• heating,

• other motorcycle modification.

The component fits in place of the original guide.

Injection-moulded plastic component

The guide is manufactured using an injection-moulding process.

This production method makes it possible to create:

• accurate geometry,

• consistent dimensions,

• smooth guiding surfaces,

• precise mounting points,

• application-specific construction.

Correct geometry is important for maintaining the intended relationship between the guide, chain and rear sprocket.

Resistance to chain abrasion

The chain continuously passes through the guide during riding and gradually wears the contact surfaces.

The material is therefore selected to withstand:

• prolonged friction,

• repeated chain movement,

• vibration,

• mechanical loading,

• dusty and muddy conditions.

The guide is still a consumable component.

Even durable plastic will eventually wear under continuous chain contact, so regular inspection remains important.

Impact resistance

The rear guide is mounted low near the rear sprocket, an area that is particularly exposed during off-road riding.

It may encounter impacts from:

• rocks,

• roots,

• rut edges,

• mud,

• flying debris.

The guide is therefore designed not only for abrasion resistance but also for mechanical durability in normal off-road use.

Inspect the component after any significant impact.

A normal wear item

Gradual wear is expected during normal use.

Wear rate depends on factors including:

• chain slack,

• motorcycle power,

• chain and sprocket condition,

• sand and mud contamination,

• riding style,

• terrain,

• cleaning frequency.

Sand, dust and chain lubricant can combine into an abrasive paste and significantly accelerate wear.

How to identify a worn guide

Inspect the guide during routine motorcycle cleaning and chain servicing.

Look for:

• deep chain grooves,

• significant material thinning,

• cracks,

• broken sections,

• deformation,

• excessive play,

• loose mounting points,

• incorrect chain travel.

Replace the guide before excessive wear begins to affect chain control.

Inspect it when replacing the chain and sprockets

Replacing the chain or sprockets is an ideal time to inspect all chain-guidance components.

Check:

• rear chain guide,

• swingarm chain slider,

• upper and lower chain rollers,

• countershaft sprocket,

• rear sprocket,

• chain adjusters,

• chain alignment,

• chain slack.

A new chain kit should operate with guide components that are also in good serviceable condition.

A worn guide can affect a new chain

If the guide surfaces are heavily worn, the chain gains additional room for unwanted movement.

This may result in:

• increased lateral movement,

• inconsistent rear-sprocket engagement,

• stronger impacts against the guide,

• additional stress on the final drive,

• accelerated wear of other parts.

Checking the guide before installing a new chain kit is therefore worthwhile.

Correct chain slack matters

A chain that is too loose can move excessively through the guide and strike it more aggressively.

A chain that is too tight increases loading throughout the final drive as the suspension moves.

Both conditions can accelerate guide wear.

Always use the motorcycle manufacturer’s specified chain-slack procedure and values.

Sand, dust and mud accelerate wear

Off-road riding naturally introduces contamination into the guide.

A mixture of:

• sand,

• dust,

• mud,

• chain lubricant

can behave like an abrasive paste.

Clean the guide area after riding and inspect the contact surfaces.

Regular cleaning also makes cracks and excessive wear easier to detect.

Straightforward installation

The precise application-specific design allows installation at the original mounting points.

Basic replacement procedure:

1. secure the motorcycle safely,

2. clean the guide area,

3. remove the original component,

4. inspect the mounting points,

5. fit the replacement guide,

6. use the appropriate hardware,

7. tighten according to the motorcycle manufacturer’s specification,

8. verify free chain movement,

9. check chain slack.

The chain must not bind or be forced out of its normal path after installation.

Available individually or in sets

Chain guides are available both individually and as parts of complete sets.

Depending on the motorcycle, you can replace:

• rear chain guide,

• swingarm chain slider,

• wear inserts,

• chain rollers,

• other related chain-guidance components.

This makes it possible either to replace a single worn part or renew a larger section of the chain-guidance system during more comprehensive servicing.

For a wide range of motorcycles

The guides are produced for specific motorcycle applications.

Versions are available for:

• KTM,

• Suzuki,

• Honda,

• Husqvarna,

• Kawasaki,

• Yamaha,

• GAS GAS,

• Royal Enfield,

• Triumph,

• CFMOTO.

Adventure-bike applications are also available, including the Yamaha Ténéré 700.

Always verify exact fitment

The guide is not a universal plastic component.

Motorcycles may differ in:

• mounting-point spacing,

• chain width,

• swingarm shape,

• rear-sprocket position,

• guide design.

Before ordering, always confirm:

• manufacturer,

• model,

• model year,

• exact motorcycle version where applicable.

Use the fitment table on the product page as the deciding reference.

A small component with a significant role in chain control

The rear chain guide may be easy to overlook, but on every ride it helps keep the drive chain correctly positioned around the rear sprocket.

Regular inspection, cleaning and timely replacement help protect the complete chain-and-sprocket system and reduce the risk of an inexpensive wear component contributing to unnecessary damage elsewhere.

When replacing the chain, do not inspect only the sprockets – check the guide components as well.
