Vortex 193BZR-45 Black 45-Tooth Aluminum Rear Sprocket

The Vortex 193BZR-45 is a 45-tooth aluminum rear sprocket finished in Vortex's durable PTFE black hardcoat anodizing — a process that bonds directly to the aluminum surface to create a harder, more corrosion-resistant finish with reduced friction compared to standard anodizing.

Engineered for motorcycle road racing, Supercross, Motocross, and high-performance street use, this sprocket is 100% CNC machined in the USA from a specially formulated 7075-T6 billet aluminum alloy. The result is a sprocket that delivers exceptional strength at a fraction of the weight of steel alternatives.

Key Features:

• 45-Tooth rear sprocket configuration
• PTFE black hardcoat finish — bonds to aluminum for superior durability and corrosion resistance
• Vortex patented saber tooth groove design — unique tooth profile engineered to extend sprocket longevity
• 100% CNC machined from 7075-T6 billet aluminum
