Vortex 313ZR-48 CAT5 Aluminum Rear Sprocket 48-Tooth 530 Pitch Black

The Vortex 313ZR-48 is a 48-tooth, 530-pitch CAT5 series aluminum rear sprocket finished in black anodize with a signature two-tone machined silver accent. Engineered for performance-minded riders and racers, this sprocket is precision CNC machined from premium 7075 aluminum and anodized before cutting to deliver both corrosion resistance and standout aesthetics.

Key Features:

• 48-Tooth / 530 Pitch: Designed for use with standard 530-pitch drive chains
• CAT5 Series Design: Vortex's iconic patented tooth profile engineered for longevity and reduced chain wear
• 7075 Aluminum Construction: Aerospace-grade alloy delivers exceptional strength at a fraction of the weight of steel sprockets
• Black Anodized Finish: Anodized prior to CNC machining for a distinctive two-tone black-and-silver appearance that resists oxidation
• CNC Machined to Tight Tolerances: Ensures concentricity for smooth, quiet operation and minimized chain wear
• Reduced Rotating Mass: Lightweight design lowers unsprung rotational weight for improved throttle response and power transfer to the pavement
• Made in the USA: Manufactured domestically to Vortex's exacting quality standards

Running a larger rear sprocket like this 48-tooth unit raises your final drive ratio, delivering stronger low-end torque and quicker acceleration at the expense of top-end speed — ideal for tight tracks or aggressive street riding. The Vortex 313ZR-48 is a direct-fit rear sprocket replacement for compatible motorcycle models using a 530-pitch chain.
