Introducing the EK 428 H/Duty Chain 104L—the updated, high-torque drive solution that supersedes the 428H. Crafted for riders and operators who push their machines to the limit, this 104-link chain is engineered to deliver precise power transfer, dependable durability, and consistent performance in demanding conditions.

Why the 104L EK 428 H/Duty Chain stands out

• 104-link precision construction ensures uniform pitch and smooth engagement with sprockets, reducing clatter and wear under heavy loads.
• Upgraded strength and reliability—the design builds on the trusted 428H with enhanced alloying and component geometry to improve fatigue resistance during aggressive acceleration and demanding rides.
• Efficient power transmission—refined roller and plate geometry minimizes friction, promoting cleaner acceleration and predictable throttle response when you need it most.
• Durable, low-maintenance durability—a protective finish and robust joint construction help resist wear from grit, moisture, and varying riding conditions, extending chain life in real-world use.
• Versatile compatibility—designed to work with standard 428 sprockets and guides, making it a straightforward upgrade for 428-series drivetrains seeking improved performance.

Ideal use cases

Perfect for sport and off-road motorcycles, ATVs, and other compact drive systems that demand high torque and dependable engagement. If you ride in challenging terrain, tow occasional gear, or simply want a longer-lasting chain that preserves drivetrain integrity, this EK 428 H/Duty Chain 104L is built to deliver.

What problems it solves

• Reduces unwanted chain stretch and irregular engagement common with lighter-duty chains under heavy load.
• Delivers steadier power delivery during hard acceleration, hill climbs, and demanding pulling scenarios.
• Extends chain life in dirty, wet, or abrasive environments thanks to a durable construction and protective finish.

Installation and care tips

For best results, pair the EK 428 H/Duty Chain 104L with compatible sprockets in good condition and follow standard 428-chain maintenance practices. Regularly lubricate with a quality chain lube, inspect for wear or stiff links, and replace worn sprockets in tandem with the chain to maintain optimal drive performance.
