Vortex 203ZK-46 CAT5 Rear Sprocket 46 Tooth

The Vortex 203ZK-46 is a high-performance rear sprocket designed for street and track motorcycles. This 46-tooth sprocket is constructed from 7075-T6 aluminum alloy, providing an optimal balance of strength and weight reduction compared to steel sprockets.

Key Features:

• 46 teeth for optimized gearing and acceleration
• 7075-T6 aluminum construction for lightweight durability
• CNC-machined from solid billet for precise tolerances
• Hard-anodized finish for wear resistance and corrosion protection
• Self-cleaning mud groove design helps prevent debris buildup
• Lightening holes reduce rotational mass without compromising strength

Vortex sprockets are engineered to exact OEM specifications and are compatible with standard 520, 525, or 530 pitch chains depending on the application. The hard-anodized surface treatment significantly extends sprocket life while maintaining consistent performance throughout the wear cycle.
