CD70 Drum Rubber – Rear Wheel Hub Damper

CD70 Drum Rubber – Quality Rear Wheel Hub Dampers

CD70 Drum Rubber is an important component fitted inside the rear wheel hub assembly. These rubber dampers help absorb shocks created when engine power is transferred through the chain and rear sprocket to the wheel. Properly functioning drum rubbers help reduce sudden drivetrain impacts, excessive play, and harsh movement during acceleration.

Made from quality rubber material, these CD70 drum rubbers are intended for motorcycle owners who want to replace worn or damaged rear hub dampers and maintain smoother everyday riding.

Key Features of CD70 Drum Rubber

• Quality Rubber Material: Designed for use as rear wheel hub dampers in compatible 70cc motorcycles.

• Shock Absorption: Helps cushion drivetrain forces when accelerating and changing throttle input.

• Reduced Excessive Play: Properly fitting, unworn rubbers help limit unnecessary movement between the sprocket carrier and rear wheel hub.

• Support for Hub Components: Helps reduce impact loads on the rear hub and sprocket carrier.

• Everyday Riding: Helps maintain smoother power delivery and reduce harsh drivetrain movement when in good condition.

What Does Drum Rubber Do in a Motorcycle?

Drum rubbers, also called rear hub damper rubbers or cush-drive rubbers, are fitted within the rear wheel hub assembly. They cushion the forces transferred from the rear sprocket carrier to the wheel.

When the rider accelerates or changes the throttle, the drivetrain experiences changes in force. The rubber dampers help absorb some of these impacts instead of allowing the metal components to transfer every shock directly.

When the rubbers become worn, compressed, cracked, or loose, the rear sprocket carrier may develop excessive movement. This can cause knocking noises, jerky power delivery, and additional stress on related components.

Compatibility with Honda and Chinese 70cc Motorcycles

According to the fitment information for this product, the drum rubber size is common across old and new CD70-style 70cc motorcycles, including Honda and Chinese-manufactured bikes.

Unlike some motorcycle components that differ according to manufacturer or model, these drum rubbers are offered for the stated common-size application. However, motorcycles can vary by manufacturer, wheel hub design, or replacement parts previously installed.

Before ordering, compare the existing rubber dampers and confirm that your motorcycle uses the same size and shape. If you are unsure, ask your motorcycle mechanic to check the fitment.

Why You Should Avoid Improvised Tyre-Rubber Substitutes

Some motorcycle owners use pieces cut from old tyres as a low-cost substitute for proper drum rubbers. However, tyre material cut and fitted as an improvised replacement may not have the correct dimensions, shape, or cushioning properties for the rear hub.

Incorrectly sized or unsuitable material may fail to fit securely, allow excessive movement or provide inconsistent shock absorption. This can increase stress on the hub and sprocket carrier.

For proper fitment and more predictable performance, use purpose-made motorcycle drum rubbers of the correct size and suitable quality rather than improvised pieces of tyre rubber.

Signs Your CD70 Drum Rubber Needs Replacement

Inspect the drum rubbers if you notice any of the following symptoms:

• Knocking or unusual noises from the rear wheel or hub area.

• Excessive movement between the rear sprocket carrier and wheel hub.

• Jerky or uneven power delivery when accelerating.

• Increased drivetrain shock when opening or closing the throttle.

• Rubber pieces that appear cracked, hardened, compressed, broken, or badly worn during inspection.

These symptoms can also be caused by a loose chain, worn bearings, or other mechanical problems. Have the rear wheel assembly inspected by a qualified motorcycle mechanic before deciding which component needs replacement.

When Should You Check or Replace Drum Rubber?

There is no single replacement interval that suits every motorcycle and riding condition. The service life depends on usage, road conditions, material quality, and maintenance.

It is sensible to ask your mechanic to inspect the drum rubbers during routine tuning or whenever the rear wheel is removed for bearing replacement, rear sprocket work, or other maintenance.

If the rubber dampers are substantially worn, cracked, broken, or no longer fit securely, replace them promptly. Severely worn dampers can allow excessive movement and may contribute to damage to the rear hub or sprocket carrier.

Installation and Maintenance Advice

• Use drum rubbers designed for the correct motorcycle hub.

• Avoid improvised tyre-rubber pieces that may not provide correct fitment.

• Inspect the rubber dampers whenever the rear wheel is removed for maintenance.

• Ask your mechanic to check the rear wheel bearings and sprocket carrier at the same time.

• Replace worn or damaged dampers as a complete set where appropriate for the hub design.

• If you notice unusual rear-wheel noises or excessive movement, have the motorcycle inspected before continuing normal use.

Frequently Asked Questions

1. What is CD70 drum rubber used for?

It is fitted inside the rear wheel hub assembly to help absorb drivetrain shocks and reduce excessive movement between the sprocket carrier and wheel.

2. Do these drum rubbers fit Honda and Chinese 70cc motorcycles?

According to the supplied fitment information, they are intended for old and new CD70-style 70cc motorcycles from Honda and Chinese manufacturers that use the same size. Confirm the hub design and dimensions before ordering.

3. Can I use pieces cut from an old tyre instead?

Using improvised tyre-rubber pieces is not recommended as a substitute for correctly sized, purpose-made drum rubbers. Incorrect fitment or cushioning may cause excessive movement and additional stress on related components.

4. What happens when drum rubbers become worn?

Worn rubbers may cause knocking noises, excessive play, and jerky power delivery. If ignored, they may contribute to wear or damage to the rear hub and sprocket carrier.

5. When should I check the drum rubbers?

Check them during routine maintenance and whenever the rear wheel is removed for bearing replacement, sprocket work, or other repairs. Replace them if they are significantly worn or damaged.

6. Can worn drum rubbers affect riding comfort?

Yes. Worn dampers may allow harsher drivetrain impacts and jerky power delivery, making the motorcycle feel less smooth during acceleration.
