In 1974, EK Chain revolutionized the drivetrain world by releasing the first O-ring sealed chain. Today, that commitment to innovation continues in a full line of motorcycle chains and hardware built to match the demands of serious riders around the world. The EK motorcycle chain with O-ring features seals the locked-in factory K3 lube while locking out any grit and debris. The result is a rugged chain that is ready for any adventure no matter the conditions.
