At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 42T-520 in Black for Kawasaki (452AZK-42) — a race-proven upgrade that swaps out heavy OEM steel for a lighter, sharper-looking, and longer-lasting drivetrain component. Vortex builds every CAT5 sprocket with a distinctive anodize-first, machine-second process, so the finished part shows off a striking black finish with contrasting silver highlights right where the material has been cut away. It's the kind of detail that separates a serious performance part from a plain replacement, and it's why Vortex sprockets have become a favorite among racers and street riders who want their bike to look as fast as it runs.

Built specifically to bolt onto compatible Kawasaki models with a 520-pitch chain and 42-tooth count, this sprocket is a direct fit for riders looking to dial in gearing while dropping unsprung weight at the rear wheel. Whether you're chasing quicker acceleration for the track or simply want a cleaner, more aggressive look on your Kawasaki, the Vortex CAT5 42T-520 is engineered to deliver both performance and style in one component.

Features:

• Anodized first, then CNC machined from 7075 aluminum for a trick colored finish with contrasting silver highlights
• 100% CNC manufactured to tight tolerances using a specially formulated alloy per Vortex specifications
• Unique "saber tooth" grooved tooth design that increases sprocket longevity and improves chain engagement
• Lightweight aluminum construction reduces rotating and unsprung mass versus OEM steel sprockets
• Black anodized finish with silver machine-cut highlights for an aggressive, race-inspired appearance
• 42-tooth, 520-pitch configuration designed as a direct-fit rear sprocket for compatible Kawasaki models
• Vortex's patented sprocket design, trusted by champions in road racing and motocross
