Vortex 193AZO-51 Aluminum Rear Sprocket Pitch Orange Sprockets - 525 51-Tooth

The Vortex 193AZO-51 is a 51-tooth, 525-pitch CNC-machined aluminum rear sprocket finished in Vortex's signature CAT5 orange anodize. Designed as a direct-fit replacement and performance upgrade for compatible BMW S1000-platform motorcycles, this sprocket delivers a significant weight reduction over OEM steel units — reducing rotating mass for sharper throttle response and improved acceleration.

Key Features:

• 51 teeth — ideal for riders seeking increased low-end torque and acceleration off the line
• 525 chain pitch — matches OEM chain specification for direct bolt-on installation
• CAT5 orange anodized finish (AZO) — vibrant color-coded anodize for a premium appearance and corrosion resistance
• 100% CNC manufactured from a specially formulated aluminum alloy per Vortex specifications
• Patented Vortex tooth design — unique profile increases sprocket longevity and chain engagement
• Lightweight construction reduces rotating mass to improve throttle response and handling
• Precision-machined for concentricity — ensures smooth, quiet operation and even chain wear
• Made in the USA by Vortex Racing
