Chain EK DEX

Durable QX-Ring Chain
The DEX series is a budget friendly sealed Quadra X-Ring (QX-Ring) chain. QX-Ring provides 1.5-2x longer chain life!

Quadra X-ring (QX-Ring) is a slim profile chain with 40% less friction than a normal O-Ring chain and 150% better endurance. Used for a variety of SRX2, 420SRX and 428ZVX series chains.

Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

Supersprox Racing steel sprocket

Supersprox Racing Steel Sprockets in sleek black finish are designed for both street and off-road motorcycles, developed on world endurance race tracks to meet high-performance demands. They feature laser-cut weight-reduction design to lower rotational mass, extra durable teeth for longer life, and tri-zinc electroplating to prevent rust and corrosion.
