Description

The Vortex Rear Sprocket is a high-performance replacement for the Yamaha YZ65. Built with a 420 pitch and available in 40 to 57 teeth, this sprocket allows for fine-tuning of gearing. It is made from top-grade 7075 T6 aluminum, reducing rotating mass and improving acceleration.

This sprocket combines durability, function, and style with anodized color options. It is precision-machined for compatibility and smooth operation, with a concentric design that reduces wear and extends drivetrain life.
