Motorcycle Chains

High-Performance Motorcycle Chains for Every Ride

Motorcycle chains are essential components of the transmission system, responsible for efficiently transferring power from the engine to the rear wheel. 

Found in a variety of vehicles — including motorcycles, motorized bicycles, mini bikes, ATVs, and go-karts — they must withstand demanding conditions while ensuring traction, stability, and long-lasting performance. 

At PGN Bearings, you'll find a wide range of chains designed to deliver strength, durability, and reliability on every ride.

What Are Motorcycle Chains?

Motorcycle chains are key components in the drivetrain system, responsible for transferring engine power to the rear wheel. 

This power transfer ensures smooth movement and control, especially in demanding conditions that require strength, traction, and precision.

Over time, natural wear and exposure to dust, debris, or moisture can affect chain performance, leading to reduced efficiency and potential safety issues. It’s essential to monitor for signs like slack, noise, or vibration and replace the chain when needed.

Types of Motorcycle Chains Available

At PGN, you’ll find various motorcycle chain types, each designed to meet the specific demands of different vehicles and applications. These chains are built with technical precision to ensure optimal performance and durability.

#420 chains for dirt bikes, ATVs, and go-karts

The #420 chain is commonly used in small-displacement motorcycles, all-terrain vehicles, and off-road go-karts. It offers high tensile strength and excellent performance in dusty, muddy, or high-vibration environments. Available in 102, 132, and 240-link versions.

415H chains for 2-stroke motorized bicycles

Perfect for 49cc to 80cc motorized bicycles, the 415H heavy-duty chain is built to handle the continuous power demands of 2-stroke engines. It’s a reliable option for urban rides or short-distance commuting with added strength and longevity.

Length Options: From 102 to 240 Links

Our motorcycle chains are available in multiple configurations to suit your project needs. All options include free connecting links and are ready for easy installation:

• #420 Chain – 102 Links;

Frequently Asked Questions (FAQ)

1. Which type of motorcycle chain is best?

It depends on your vehicle and usage. #420 chains are ideal for motorcycles up to 125cc and off-road setups, while 415H chains are suited for 2-stroke motorized bicycles. Always check the manufacturer's specs.

2. How do I know what chain my motorcycle needs?

Refer to your vehicle’s manual or check the markings on your old chain. Chain numbers (like 420 or 415H) indicate specific dimensions such as pitch and inner width.

3. What does a 520, 420, or 428 chain mean?

These are ANSI-standard codes. The first digit refers to pitch (distance between pins), and the next two refer to inner width. For example, a 420 chain has a 0.5" pitch and 6.25 mm inner width.

4. Are 420 and 428 chains the same?

No. While both have the same pitch (0.5"), the 428 chain is wider. They're not interchangeable — always match the chain to your sprockets.

5. Do PGN motorcycle chains come with connecting links?

Yes. All models in this category include free connecting links to simplify installation and chain length adjustment.
