The Vortex 604ZL-55 is a high-performance 55-tooth rear sprocket designed for sport bikes and stunt applications. This lightweight aluminum sprocket is constructed from premium 7075-T6 aerospace-grade aluminum alloy, offering an optimal balance of strength and reduced rotating mass for improved acceleration and performance.

Key Features:

• 55-tooth configuration ideal for stunt riding and wheelie applications
• 7075-T6 aluminum construction for maximum strength-to-weight ratio
• Vortex patented tooth design increases sprocket longevity
• Silver anodized finish (standard for 55+ tooth sprockets)
• Precision CNC machined for accurate fitment
• Lightweight design reduces rotating mass for better throttle response

This oversized rear sprocket provides significant gearing changes for riders looking to optimize low-end acceleration and torque delivery. The weight savings on drivetrain components is multiplied as rotating mass, making this aluminum sprocket an excellent performance upgrade over heavier steel alternatives.
