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.
428H heavy-duty design boosts tensile strength, easily handling torque loads from 125–400cc engines without stretching or snapping.
Heat-treated (HRC 52–56) rollers, pins, and plates minimize abrasion, extending service life by 30% vs. standard 428 chains.
Zinc plating or black oxide coating prevents rust and oxidation, adapting to wet, dusty, or humid riding environments.
102-link length directly fits popular models (e.g., Honda CB300, Yamaha YBR250), enabling quick, tool-friendly replacement.
Fits 125–400cc cruisers, nakeds, and sport bikes (e.g., Kawasaki Ninja 300) as the primary drivetrain chain.
Used in 150–250cc off-road models (e.g., Suzuki DR-Z250) for reliable power transfer on rough terrain.
Compatible with 150–350cc ATVs/UTVs for work or recreational off-road use.
Ideal for DIY projects or replacement where 428H pitch and 102-link length are specified.

"428H" represents the heavy-duty (H) 428-series pitch of 12.7mm (0.5 inch), designed for higher torque resistance. "102L" indicates that the chain has 102 links, a common length for 125–400cc motorcycles.
It is highly compatible with 125–400cc 4-stroke engine motorcycles, including street bikes (like Honda CB300, Yamaha YBR250), dual-sport dirt bikes, and light ATVs/UTVs.
The chain is made of high-quality heat-treated alloy steel (40CrMnMo), providing extra strength and resistance to stretching under load.
Yes, the chain undergoes surface treatments like zinc plating or black oxide coating to prevent rust and oxidation in humid or wet environments.
With regular lubrication and proper maintenance, the typical service life ranges between 15,000 and 25,000 km.
For most standard models designed for a 102-link configuration, it is pre-calibrated to fit directly without needing link cutting, ensuring a hassle-free installation.
