At DMG Motorsports, we present the Vortex F5 Rear Aluminum Sprocket 48T-530 in Black Hardcoat (840K-48) — a race-proven upgrade engineered for Yamaha riders who demand less rotating mass and more confidence at the rear wheel. Vortex has built its reputation supplying championship-winning sprockets to racers across every class, and the F5 series is where that pedigree really shows. Each sprocket is precision CNC machined in the USA from a specially formulated 7075 aluminum alloy, then hard anodized with a jet-black dye and finished with a PTFE hard-coat for a durable, low-friction surface that resists wear and keeps cleanup simple. The result is a lighter, stronger sprocket than a stock steel unit, translating to quicker acceleration and sharper handling without sacrificing durability on the street or the track.
