• Vortex Patented Tooth Design — Unique tooth profile increases sprocket longevity and reduces chain wear
• Weight-Reducing Pockets — Strategic material removal lowers unsprung and rotating weight for improved throttle response

Reducing rotating mass with a lightweight aluminum sprocket like the 592ZK-43 helps put more power to the pavement and sharpens throttle response. The durable black anodized finish holds up through the elements, keeping the sprocket looking and performing great mile after mile.
