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" refers to the heavy-duty (H) 428-series pitch of 12.7mm (0.5 inch), designed for enhanced tensile strength. "102L" indicates that the chain length consists of 102 individual links.
This chain is designed to match the OEM specifications of 125cc to 400cc displacement motorcycles, including popular street bikes, dual-sport and dirt bikes, and light utility vehicles (ATVs/UTVs).
For motorcycles that natively require a 102-link chain (such as the Honda CB300 or Yamaha YBR250), the chain fits directly without any need for link cutting or modifications.
Under typical motorcycle operating conditions and with regular lubrication, the chain offers a service life of approximately 15,000 to 25,000 km.
The chain features a surface treatment of either zinc plating or black oxide coating, which provides anti-rust and anti-oxidation protection in wet, dusty, or humid riding conditions.
It is manufactured using heat-treated alloy steel (40CrMnMo) with rollers, pins, and plates hardened to HRC 52–56, achieving a minimum tensile strength of 3,800 N.
