Strike Shadow 420H Heavy-Duty Chain

Put your Strike Shadow’s torque to work with a chain built for the load. This 420H heavy-duty chain from Strike Cycles uses reinforced side plates and heat-treated steel to handle the increased torque demands of electric mini-moto and e-moto platforms.

Compared with standard 420 chains, its thicker side plates provide added strength and durability, helping reduce stretch and wear under hard acceleration. The 420H designation identifies a reinforced version of the 420 chain size, retaining the standard 1/2” pitch. It’s a practical upgrade for demanding riding, though regular lubrication and correct chain adjustment still matter for drivetrain life.
