Vortex 635ZK-38 Steel Rear Sprocket 630 Pitch 38-Tooth Kawasaki

The Vortex 635ZK-38 is a 38-tooth, 630-pitch steel rear sprocket designed for Kawasaki motorcycles. Built to Vortex's exacting standards, this sprocket delivers the ideal balance of durability, weight, and performance for street and sport riding applications.

Key Features:

• Carbon steel construction — electroplated with a satin black finish for corrosion resistance
• 630 chain pitch — heavy-duty sizing for high-displacement motorcycle applications
• 38-tooth rear sprocket — provides a stock-equivalent or performance-tuned gear ratio
• Hardened teeth — engineered to withstand extended use without loss of strength or precision
• Cupped face design — reduces overall sprocket weight while maintaining structural integrity
• Vortex patented tooth profile — unique geometry increases sprocket longevity compared to standard designs
• Kawasaki-specific carrier fitment (ZK) — designed to bolt directly onto compatible Kawasaki rear wheel hubs

Vortex sprockets are manufactured to precise tolerances, resulting in a component that runs concentrically, quietly, and reliably mile after mile. The 635ZK-38 is an excellent OEM replacement or upgrade for riders seeking a long-lasting, performance-oriented rear sprocket on their Kawasaki motorcycle.
