At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 41T-520 in Silver (654A-41) — a genuine race-industry standard built for Yamaha riders who demand precision, durability, and reduced rotating mass. Vortex has built a reputation as one of the most trusted names in drivetrain components, and this sprocket carries that legacy forward with its lightweight construction and unique tooth profile designed to keep your chain running smooth and quiet, lap after lap.
