At DMG Motorsports, we present the Vortex F5 Rear Sprocket in 40T, 520 pitch, finished in black hardcoat (PN 654AK-40) — a race-bred aluminum sprocket built to shed weight and hold up to serious abuse on the street or the track. Vortex has been trusted in the pits of championship-winning teams for years, and this F5 sprocket brings that same race-proven engineering to your bike. Each sprocket is machined from 7075 T6 aluminum to a very high tolerance, giving you a component that is both incredibly strong and dramatically lighter than a stock steel sprocket, which helps cut rotating mass for snappier acceleration and sharper handling.

The F5's signature finish starts with a type 3 hard anodizing process using a jet black dye, then a PTFE topcoat is applied for extra lubricity and long-term wear resistance. The result is a sprocket that not only looks aggressive but stays cleaner and lasts longer than typical aluminum sprockets. Combined with Vortex's unique tooth profile, this sprocket is engineered to maximize chain life and sprocket longevity, making it a smart upgrade for riders who demand performance without sacrificing durability.
