Vortex 414ZK-42 CAT5 Aluminum Rear Sprocket 42T Black

The Vortex 414ZK-42 is a 42-tooth CAT5 aluminum rear sprocket finished in black with silver machined accents. Built for performance-minded riders, this sprocket is anodized first and then CNC machined from 7075 aluminum, producing a striking two-tone appearance while maintaining precise tolerances throughout.

Key Features:

• CAT5 Aluminum Construction — Lightweight 7075 aluminum reduces rotating mass for improved throttle response and acceleration
• Black Anodized Finish — Anodized before CNC machining for a durable color layer with bright silver highlights on tooth faces
• 100% CNC Manufactured in the USA — Machined to tight tolerances for consistent fitment and performance
• Vortex Patented Tooth Design — Unique tooth profile engineered to extend sprocket longevity and promote smooth chain engagement
• Specially Formulated Alloy — Material spec developed exclusively by Vortex for the ideal balance of strength and weight savings
• 42 Teeth — Rear sprocket tooth count for tuning final drive ratio

Vortex sprockets are a proven choice on road courses, tracks, and the street. The CAT5 aluminum construction keeps unsprung and rotating weight to a minimum, helping translate more engine output into forward motion. The 414ZK-42 is a direct bolt-on replacement and tuning upgrade for compatible motorcycles.
