Vortex 829CZK-50 50-Tooth Aluminum Rear Sprocket

The Vortex 829CZK-50 is a high-performance 50-tooth aluminum rear sprocket designed as a direct replacement or upgrade for compatible motorcycles. Engineered by Vortex Racing — a trusted name in powersports drivetrain components — this sprocket delivers a strong balance of lightweight construction and durable performance for street and track applications.

Key Features:

• 50-Tooth Rear Sprocket for modified gear ratio and acceleration tuning
• Lightweight aluminum construction reduces unsprung rotational mass for improved handling and throttle response
• Hard anodized finish for corrosion resistance and long service life
• CNC machined to precise tolerances for smooth, consistent chain engagement
• Direct OEM-style fitment using the 829 bolt pattern for easy installation
• Compatible with standard motorcycle drive chains

The 829CZK-50 is an ideal choice for riders looking to fine-tune their bike's power delivery. A higher tooth count lowers the overall gear ratio, improving low-end acceleration and reducing top speed — a popular modification for tight circuits and technical riding environments. Vortex sprockets are manufactured to strict quality standards and are a popular OEM-replacement and performance upgrade option in the motorcycle community.
