At DMG Motorsports, we present the Vortex F5 Rear Sprocket 41T-520 in Black Hardcoat (251AK-41) - a race-proven, lightweight aluminum sprocket engineered to give your Honda a real edge in acceleration and handling. Built by Vortex Racing, a company trusted in Motocross, Supercross, Road Racing, and Flat Track paddocks, this sprocket swaps out heavy OEM steel for a purpose-built 7075 aluminum alloy piece that sheds rotating mass without sacrificing durability. Whether you're chasing lap times at the track or simply want a cleaner, more responsive drivetrain, this 41-tooth 520-pitch sprocket delivers the strength, precision fit, and aggressive black finish that Vortex is known for.

Features:

• CNC machined from 7075 aluminum for an excellent strength-to-weight ratio versus heavier steel sprockets
• Hard anodized with a jet black dye for a durable, corrosion-resistant, aggressive finish
• PTFE black hardcoat treatment that increases wear resistance and adds extra lubricity for a longer service life
• Unique, patented tooth design that increases sprocket longevity and improves chain engagement
• Lighter than OEM steel sprockets, reducing rotating mass for improved acceleration and handling
• 100% CNC manufactured in the USA from a specially formulated alloy per Vortex specifications
• 41-tooth, 520-pitch configuration designed as a direct fit for compatible Honda sportbike models
• Trusted by champions - developed and proven by a company owned and operated by racers and enthusiasts
