At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 40T-520 in Silver (211-40) — the sprocket that has become the "Standard" in the race industry. Built for riders who demand a lighter, stronger alternative to OEM steel, this Vortex sprocket is precision CNC machined from 7075 aluminum and finished with an electrically coated silver surface for a brighter shine. Designed as a direct 520-pitch fitment for the Honda CBR250R, it delivers a noticeable reduction in rotating mass that translates into snappier acceleration and improved handling, all while being trusted by champions across the paddock.

Features:

• CNC machined from lightweight, high-strength 7075 aluminum
• Electrically coated silver finish for a brighter shine and added surface durability
• Unique, patent-pending saber tooth design for smooth chain engagement
• 520 pitch, 40-tooth configuration built for Honda CBR250R applications
• Reduced rotating mass versus OEM steel sprockets for quicker acceleration and sharper handling
• Precision engineered to the tight tolerances that have earned Vortex the trust of race teams and champions
