Whether
you race your quad, ride just for fun, or use one for work, EK is
your best choice when you need a chain. EK’s exclusive Quadra-X
Ring seal gives our chains at least 50% longer service life and dramatically
reduced friction, compared with standard O-ring chains. Sideplate
holes reduce weight, inhibit friction, dissipate heat, extend seal
life, and facilitate self-cleaning.
