At DMG Motorsports, we present the Vortex F5 Rear Sprocket 46T-520 in Black Hardcoat (Part# 452AK-46) — a race-proven aluminum rear sprocket engineered to shed unsprung weight and sharpen acceleration without sacrificing durability. Built on Vortex's patented F5 tooth profile, this sprocket is 100% CNC manufactured in the U.S.A. from a specially formulated 7075 aluminum alloy, then finished with a jet-black hardcoat anodizing and PTFE topcoat for a slicker, longer-lasting drivetrain component. Whether you're chasing lap times on the track or want a lighter, better-looking replacement for your OEM steel sprocket, this Vortex F5 delivers the strength-to-weight ratio and corrosion resistance riders have trusted for decades.

Features:

• CNC machined from 7075 aircraft-grade aluminum for maximum strength at minimal weight
• Hard anodized (Type II) with a jet-black dye for a durable, corrosion-resistant finish
• PTFE coated over the hardcoat anodizing for added lubricity and extended wear life
• Unique patented Vortex tooth design increases sprocket longevity and drivetrain smoothness
• 100% CNC manufactured in the U.S.A. from a specially formulated Vortex alloy
• 46-tooth count, 520 pitch — ideal for OEM replacement or 520 chain conversions
• Lightweight aluminum construction reduces rotating mass for improved acceleration and handling
• Trusted by champions and used on race-proven Vortex sprockets since 1995
