• 58-tooth rear sprocket for fine-tuned gear ratio adjustment
• CAT5 aluminum construction — lightweight design reduces rotating mass and improves throttle response
• Black anodized finish for corrosion resistance and clean aesthetics
• 100% CNC machined to tight tolerances for precise fitment and concentricity
• Hardened teeth for long service life and consistent chain engagement
• Drilled lightening holes further reduce weight without sacrificing strength

Vortex Racing rear sprockets are a trusted choice among street and track riders seeking performance upgrades or direct OEM replacements. The 201ZK-58 is ideal for riders looking to increase low-end acceleration and torque delivery by running a larger rear tooth count.
