The EK 420 SRO Series Drive Chain is a durable, value-focused replacement chain for powersports applications requiring dependable performance and long service life. Manufactured by EK Chain, this 120-link chain features heat-treated steel alloy construction designed to withstand repeated drive loads, vibration, and everyday riding conditions.
O-ring seals help retain factory-applied lubricant inside the chain joints while helping prevent dirt, grit, and other contaminants from entering. This sealing design supports smooth operation, reduces wear, and helps maintain consistent chain performance between maintenance intervals. The chain is supplied with a clip-type connecting link for installation and service convenience.
Designed for compatible motorcycles, ATVs, and other powersports vehicles using a 420-size drive chain, the EK 420 SRO Series provides a practical fit for applications specified for a 420 chain with 120 links. Always verify the vehicle manufacturer’s chain size, link count, and fitment requirements before installation.
