Vortex CK6404 Black Chain and Sprocket Kit

The Vortex CK6404 is a complete black chain and sprocket kit engineered for street and performance motorcycle applications. Vortex Racing is a U.S.-based manufacturer with a proven track record in road racing, supercross, and motocross, producing drivetrain components built to tight tolerances with premium materials.

Kit Includes:

• Steel front (countershaft) sprocket
• Laser-cut steel rear sprocket with black finish
• High-performance X-ring chain with rivet-type master link

Key Features:

• X-Ring Chain Technology — reduces friction and extends service life compared to standard O-ring chains
• Laser-Cut Steel Rear Sprocket — precision-cut for consistent tooth geometry and long wear life
• Chromoly Steel Front Sprocket — hardened for maximum durability at the countershaft
• Stock Gearing — kit is configured to OEM gear ratios for direct replacement
• Rivet-Type Master Link included for secure chain assembly

Installation Note: X-ring chains are wider than standard roller chains. When fitting to a motorcycle originally equipped with a non-O-ring chain, verify adequate clearance at the engine cases near the countershaft sprocket before installation.

The Vortex CK6404 chain and sprocket kit delivers a reliable, performance-grade drivetrain upgrade, making it an excellent OEM replacement or a step up from a worn stock setup.
