Vortex 523ZB-48 Black Aluminum 520-Pitch 48-Tooth Rear Sprocket

The Vortex 523ZB-48 is a 48-tooth, 520-pitch aluminum rear sprocket finished in black, engineered for motorcycle riders who demand precision, durability, and performance. Built in the USA by Vortex Racing, this sprocket is part of the brand's well-established lineup of CNC-machined rear sprockets trusted by racers and street riders alike.

Key Features:

• 520 Pitch: Designed for use with standard 520-pitch drive chains
• 48 Teeth: Provides a taller rear gearing ratio suitable for a wide range of performance applications
• Black Anodized Finish: Electro-plated or anodized black coating resists corrosion and provides an aggressive, race-ready appearance
• 100% CNC Machined: Manufactured in the USA to precise tolerances for concentricity and consistent chain engagement
• Specially Formulated Aluminum Alloy: Lightweight construction reduces rotating mass for improved throttle response and acceleration
• Patented Tooth Design: Vortex's unique tooth geometry increases sprocket longevity and promotes smooth, efficient power transfer
• Lightening Holes: Strategic cutouts further reduce unsprung rotational weight

The Vortex 523ZB-48 rear sprocket is an ideal upgrade or direct replacement for riders looking to fine-tune their gear ratios or replace a worn OEM sprocket with a high-quality, race-proven component. As with all Vortex sprockets, it is recommended to replace the chain and front sprocket simultaneously for optimal performance and longevity.
