The Vortex 154ZR-49 is a 49-tooth aluminum rear sprocket from Vortex Racing's CAT5 lineup, designed for high-performance street and track use.

• Lightweight aluminum construction reduces rotating mass for improved performance
• Red anodized finish (ZR suffix) for corrosion resistance and visual appeal
• Vortex patented tooth design for extended sprocket longevity and smooth chain engagement
• CNC precision-machined to exact tolerances for concentricity and quiet operation
• Part of the Vortex CAT5 rear sprocket series

Vortex Racing sprockets are a popular choice among both street riders and racers looking to fine-tune their final drive ratio for better acceleration, improved corner exit drive, or track-specific gearing setups.
