Vortex 317ZKV4-41 V4 Aluminum Rear Sprocket 41T

The Vortex 317ZKV4-41 is a 41-tooth aluminum rear sprocket featuring Vortex's new V4 sprocket design, introduced in 2026 as an evolution of the iconic CAT5. The V4 pattern delivers a 10–15% reduction in weight over the CAT5 without sacrificing structural integrity, thanks to machined faces on both sides and an optimized material removal pattern focused on maximum strength retention.

Key Features:

• V4 Design: Vortex's latest sprocket architecture offering 10–15% less weight than the classic CAT5 pattern
• 41 Teeth: Allows precise gear ratio tuning for acceleration or top-speed optimization
• Aerospace-Grade Aluminum: Lightweight construction reduces rotating mass for improved throttle response and handling
• 100% CNC Machined: Precision-manufactured in the USA to exact tolerances
• Anodized Finish: Clear-coat or color anodizing applied before cutting for the signature two-tone machined look and oxidation protection
• Saber Tooth Groove Design: Vortex's proprietary tooth profile for optimized chain engagement and longevity

Aluminum sprockets are the preferred choice for road racing, motocross, flat track, and drag racing applications where weight savings are critical. For best results, keep the chain cleaned and properly tensioned every 300–400 miles to maximize sprocket life.
