Vortex 628ZK-56 CAT5 Aluminum Rear Sprocket 56-Tooth 415 Pitch

The Vortex 628ZK-56 is a 56-tooth CAT5 aluminum rear sprocket designed for 415-pitch chain applications. Manufactured by Vortex Racing in the USA, this sprocket is precision-engineered for riders seeking a lightweight, high-performance alternative to heavy OEM steel sprockets.

Vortex Racing sprockets are crafted from a specially formulated aluminum alloy to Vortex's own specifications, then 100% CNC machined to exacting tolerances. The result is a sprocket that is concentric, stronger, and more consistent than mass-produced alternatives. A silver anodized finish protects against corrosion and oxidation for long service life.

Key Features:

• 56-tooth rear sprocket for tuning final drive ratio
• 415 pitch chain compatibility
• Lightweight CAT5 aluminum construction reduces rotating mass
• 100% CNC manufactured in the USA
• Specially formulated alloy per Vortex specifications
• Silver anodized finish for corrosion resistance
• Vortex patented tooth design for increased sprocket longevity
• Precision machined for concentric fit and reduced chain wear

Reducing rotating mass with a lightweight aluminum sprocket helps improve throttle response and overall powertrain efficiency. The higher 56-tooth count provides increased low-end torque and acceleration compared to lower-count sprockets. Vortex Racing has been a trusted name in motorsports for over 15 years, supplying components to professional race teams worldwide.
