Vortex 414EZK-48 Black 48-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 414EZK-48 is a 48-tooth, 520-pitch aluminum rear sprocket finished in black anodize, engineered for motorcycle riders seeking a high-performance, lightweight alternative to OEM steel sprockets. Part of Vortex's proven 414-series lineup, this sprocket is 100% CNC-machined in the USA from a specially formulated aluminum alloy to exacting tolerances, ensuring a perfectly concentric fit that protects both your chain and sprocket for extended service life.

Key Features:

• 520 Chain Pitch — direct OEM replacement or suitable 520-pitch conversion fitment
• 48 Teeth — increases rear drive ratio for improved low-end torque and acceleration
• Lightweight Aluminum Construction — significantly reduces rotating mass compared to steel, translating to quicker throttle response
• 100% CNC Machined in the USA — manufactured to the tightest tolerances for perfect concentricity every time
• Black Anodized Finish — corrosion-resistant coating applied before cutting, resulting in Vortex's signature two-tone machined appearance
• Vortex Patented Tooth Design — reduced drag and friction for improved acceleration and deceleration, with enhanced sprocket longevity
• Weight-Saving Cutouts — strategic material removal further lowers unsprung and rotating weight

Vortex aluminum sprockets are the preferred choice for road racing, motocross, flat track, and performance street riding. For best results, ensure your chain is properly tensioned and cleaned every 300–400 miles to maximize the life of this sprocket. Available in single-tooth increments across the 414EZK series.
