EK 530-120 SRX2 Chain – QX-Ring

High‑Performance Drive Chain with Extended Life and Reduced Friction

The EK 530 SRX2 QX‑Ring chain from EK Chain is engineered for reliable power delivery, extended service life, and optimal efficiency in sealed drive applications. Featuring advanced Quadra X‑Ring (QX‑Ring) technology and a sealed design, the SRX2 series significantly reduces internal friction compared to conventional chain designs. Toxic Moto Racing

QX‑Ring seals improve lubrication retention and decrease wear on contact surfaces, resulting in a service life approximately 1.5 to 2 times longer than standard O‑Ring chains. Weight‑reducing holes in the links help minimize rotating mass, enhancing throttle response and overall drivetrain efficiency. Toxic Moto Racing
