Product Description

Product Overview

The 428H*102L is a high-performance roller chain tailored for motorcycle drivetrains, where reliable power transfer between engine and wheels is critical. Its "428H" code refers to the universal heavy-duty (H) 428-series pitch (12.7mm/0.5 inch)—optimized for enhanced tensile strength to handle high torque from mid-displacement engines. The "102L" denotes a 102-link length, calibrated to match OEM specs of 125–400cc motorcycles, eliminating the need for link cutting during installation.

Key Advantages

1. High Torque Endurance

428H heavy-duty design boosts tensile strength, easily handling torque loads from 125–400cc engines without stretching or snapping.

2. Long-Lasting Wear Resistance

Heat-treated (HRC 52–56) rollers, pins, and plates minimize abrasion, extending service life by 30% vs. standard 428 chains.

3. All-Condition Protection

Zinc plating or black oxide coating prevents rust and oxidation, adapting to wet, dusty, or humid riding environments.

4. Hassle-Free Installation

102-link length directly fits popular models (e.g., Honda CB300, Yamaha YBR250), enabling quick, tool-friendly replacement.

Applications

1. Mid-Displacement Street Bikes

Fits 125–400cc cruisers, nakeds, and sport bikes (e.g., Kawasaki Ninja 300) as the primary drivetrain chain.

2. Dual-Sport & Dirt Bikes

Used in 150–250cc off-road models (e.g., Suzuki DR-Z250) for reliable power transfer on rough terrain.

3. Light Utility Vehicles

Compatible with 150–350cc ATVs/UTVs for work or recreational off-road use.

4. Custom Motorcycle Builds

Ideal for DIY projects or replacement where 428H pitch and 102-link length are specified.

Frequently Asked Questions (FAQ)

What does the "428H*102L" specification stand for?

The "428H" represents a heavy-duty 428-series pitch measuring 12.7mm (0.5 inch), designed for enhanced tensile strength. The "102L" indicates that the chain consists of exactly 102 link lengths, pre-calibrated to fit specific motorcycle models without needing to be cut.

Which engine sizes is this roller chain designed for?

This drivetrain roller chain is optimized for mid-displacement motorcycles with 125cc to 400cc 4-stroke engines, providing reliable torque and power transfer.

How does the "H" (Heavy-Duty) designation benefit my motorcycle?

The heavy-duty design boosts the chain's minimum tensile strength to 13,800 N (854 lbs). This prevents stretching or snapping under high torque loads from mid-displacement engines.

What materials are used to ensure the chain's durability?

The chain is constructed from heat-treated alloy steel (40CrMnMo) with a surface treatment of either zinc plating or black oxide coating to provide anti-rust and anti-oxidation protection in harsh environments.

What is the typical service life of the 428H*102L chain?

With regular lubrication and proper maintenance, the chain delivers a typical service life ranging between 15,000 and 25,000 km.

Can this chain be used in extreme temperatures?

Yes, this chain is engineered to operate efficiently across a wide temperature range, specifically from -25°C up to 160°C (-13°F to 320°F).
