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.
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.
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.
