Vortex 920ZK-32 Aluminum Rear Sprocket 32-Tooth 920 Pitch

The Vortex 920ZK-32 is a lightweight, CNC-machined aluminum rear sprocket featuring 32 teeth and designed for 920 pitch chain applications. Precision-engineered by Vortex Racing in the USA, this sprocket delivers a significant weight reduction over stock steel sprockets, helping to lower rotating mass for improved throttle response and acceleration.

Key Features:

• 32-Tooth / 920 Pitch — direct-fit replacement or performance upgrade for 920 pitch chain setups
• Aerospace-grade aluminum construction — reduces unsprung rotating mass compared to OEM steel sprockets
• 100% CNC machined — manufactured to tight tolerances for consistent fit and long service life
• Anodized finish — protective clear or color anodize applied before cutting, producing the iconic two-tone machined look
• Vortex CAT5 patent-pending tooth design — saber tooth profile engineered to maximize sprocket longevity and chain engagement
• Made in the USA — Vortex Racing has manufactured race-quality sprockets domestically for over 20 years

Vortex aluminum rear sprockets are a proven choice for street riders and racers looking to shed drivetrain weight and fine-tune their gear ratios. Always replace the front sprocket and drive chain at the same time to ensure proper wear and chain life.
