The Vortex 827ZR-50 is a premium CAT5 aluminum rear sprocket featuring 50 teeth and a durable zinc-plated finish. Engineered from 7075-T6 aluminum alloy, this sprocket delivers an exceptional strength-to-weight ratio that significantly reduces rotating mass compared to steel sprockets while maintaining excellent durability.

Key Features:

• 50-tooth configuration for optimized gearing options
• CNC-machined from aerospace-grade 7075-T6 aluminum
• Zinc-plated finish (ZR) for enhanced corrosion resistance
• CAT5 design with weight-reducing material removal
• Precision-cut teeth for smooth chain engagement and extended chain life
• Hard-anodized surface treatment for wear resistance
• Laser-etched tooth count and Vortex branding

Vortex CAT5 sprockets are designed for sportbike and performance motorcycle applications where reducing unsprung weight improves acceleration, handling, and overall performance. The zinc plating provides additional protection against the elements while maintaining the sprocket's structural integrity during aggressive riding conditions.
