Warp 9 54T CNC Billet Rear Sprocket (Black / Gold)
7075-T6 billet alloy 54-tooth sprocket giving 12% more low-end torque for aggressive singletrack and hill climbs.

Professional grade non-O-ring motocross chain with SDH pin treatment for minimal friction and maximum tensile strength.
The DID 420 NZ3 Gold Racing Chain is the definitive drivetrain upgrade for electric dirt bike riders experiencing chain stretch, premature wear, or linkage slap from stock chains that cannot withstand the instant peak torque delivery of high-performance electric motors. DID's SDH pin treatment hardens chain pins against the shock loading that electric motor torque generates — conventional bicycle-grade chains can stretch by 1–2% within 10 hours of electric dirt bike use under aggressive riding conditions. At 22.0 kN (4,930 lbs) tensile strength, the NZ3 handles the full peak torque output of 72V controller-tuned electric bikes without fatigue. Gold outer plates provide active corrosion resistance in wet Australian mud, creek crossings, and salt-air coastal conditions that rapidly corrode cheaper chains. The 112-link kit with included clip-type master link fits standard 420-pitch electric dirt bike sprocket configurations. Available from Electric Dirt Bike Australia with full chain care kit recommendations.
