KEY FEATURES OF EK CHAINS

1. ANALYTIC TECHNOLOGY

• State-of-the-art advanced computer technology enables EK to reduce the overall weight by 3% without compromising tensile strength, which in turn extends the life of the chain
• Industry leading machining process of all metal surfaces helps create an unmatched and optimal seal of all EK O-Ring and X-Ring chains
• Additionally mud and dirt build-up is significantly reduced via this technology

2. HEAT TREATMENT

• All EK off-road race chains utilise EK’s exclusive CRH pin treatment process, which provides an extremely hard outside coating and softer inside to increase strength and reduce wear
• Superior impact and shock absorption, and reduced oxidation is also a result of EK’s Chromium Carbide pin surface coating

4. SEAL-RING TECHNIQUE

O-Ring - EK O-Ring chain has excellent performance at a great price. EK Chain was at the forefront of Sealed chain development and manufacture in the early 70’s, first used as genuine chain on the Kawasaki Z1. O’ring used for SRO Series.

QX-Ring - QX-Ring is a Slim Profile chain with 40% less friction than a normal O-ring chain and 150% better endurance. Used for SRX2 series, 420SRX and 428ZVX.

NX-Ring - NX-Ring is 15% more durable than QX-Ring. The NX-Ring chain has improved tensile strength & increased weight saving. Used for ZVX3 Series.

SX-Ring - SX-Ring is EK’s slimmest profile X-Ring. High tensile strength and increased durability. Used for 520 RXO/SM Series.
