At DMG Motorsports, we present the Vortex CAT5 Rear Aluminum Sprocket 42T-530 in Black (Part #427ZK-42) — a stock-replacement rear sprocket engineered for Kawasaki ZX-14 models. Built by Vortex, a name trusted in racing circles for tight-tolerance, high-performance drivetrain components, this sprocket swaps the heavier factory steel unit for a lighter, race-proven aluminum design that helps reduce rotating mass and sharpen your bike's power delivery to the pavement. Finished in sleek black with striking silver highlights, it looks as fast as it performs, whether you're carving up the track or upgrading your street bike's drivetrain.

Features:

• Anodized FIRST then CNC machined from premium 7075 aluminum for a durable, lightweight build
• Trick black anodized finish with contrasting silver highlights for a distinctive race-ready look
• Unique tooth design engineered for improved chain engagement and extended sprocket life
• Lightweight aluminum construction reduces rotating mass to help amplify power transfer to the ground
• Trusted by champions - a favorite among racers for its tight tolerances and reliable performance
• 42-tooth, 530-pitch configuration designed as a direct stock replacement for compatible Kawasaki ZX-14 models
