Vortex V3 2.0 520Rrx4 Chain The Vortex RX3 Series Chain is engineered for peak performance and endurance on race tracks, boasting more robust chain links than the SX3 Series for greater tensile strength and displacement. With its advanced Tri-glide X-rings, featuring three pockets of lubrication and two stabilizers, it significantly cuts down heat and friction for up to a tenfold increase in lifespan compared to standard O-ring chains. Inner plate cutouts minimize the chain's weight, enhancing acceleration, braking and handling by reducing rotating mass. Features: Additional strengthening for racing Drilled links reduce rotating mass Tri-glide X-ring seals to reduce friction and increase chain life Improved tensile strength Corrosion-resistant finish Compatible displacement: 1,000cc Road Race/Track use only Tensile strength: 8,500 lbs Includes rivet type connecting link
