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.

The "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 contains 102 links, which matches the standard OEM configurations of many 125–400cc motorcycles.
For motorcycles that specify a 102-link configuration (such as the Honda CB300 or Yamaha YBR250), this chain directly fits and eliminates the need for link cutting during installation.
This chain uses heat-treated (HRC 52–56) alloy steel (40CrMnMo) rollers, pins, and plates. This process minimizes wear and abrasion, delivering up to 30% longer service life compared to standard 428 chains.
Yes, it is highly suited for off-road environments. Its zinc plating or black oxide surface treatment provides reliable rust and oxidation protection, making it ideal for wet, dusty, or muddy conditions.
Under normal motorcycle use conditions and with regular proper lubrication, the chain typically delivers a service life of 15,000 to 25,000 km.
It is compatible with all 428H-specification sprockets featuring 13 to 45 teeth, operating optimally on 125–400cc 4-stroke engines.
