Vortex 150ZR-55 530-Pitch 55-Tooth Steel Rear Sprocket

The Vortex 150ZR-55 is a 530-pitch, 55-tooth steel rear sprocket engineered for sport and performance motorcycles. Built to Vortex's exacting standards, this sprocket is manufactured from carbon steel alloy and features a corrosion-resistant finish — either silver anodized or electro-plated satin black — for long-lasting durability in demanding riding conditions.

Vortex Racing's patented tooth geometry sets this sprocket apart from standard replacements, promoting more even chain wear and extending overall drivetrain life. Precision manufacturing ensures concentricity and quiet, smooth operation cycle after cycle.

Key Features:

• Chain Pitch: 530
• Tooth Count: 55 teeth
• Material: Carbon steel alloy per Vortex specifications
• Finish: Silver anodized or electro-plated satin black for corrosion resistance
• Patented tooth design for increased sprocket longevity and reduced chain wear
• Precision-manufactured for concentricity and quiet operation

A 55-tooth rear sprocket increases the drive ratio compared to a stock sprocket, delivering stronger low-end torque and improved acceleration — ideal for riders who want more responsive throttle response. This sprocket is a direct-fit replacement for compatible sport and performance motorcycles using a 530-pitch chain and the 150ZR bolt pattern.
