At DMG Motorsports, we present the Vortex Standard Aluminum Rear Sprocket, 43-Tooth, 525 Pitch in Silver (Part No. 654-43) — a fitment for select Yamaha models and a mainstay in the sprocket world for good reason. Vortex has long been the benchmark against which other race sprockets are measured, and this Standard Series piece delivers that reputation directly to your drivetrain. Built for riders who demand consistent, dependable performance whether on the street or the track, this sprocket combines low weight with high strength so your bike can accelerate harder and handle better without sacrificing durability.

Every Vortex Standard sprocket is precision CNC machined from 7075 aluminum, a material choice that racing teams rely on for its exceptional strength-to-weight ratio. The Vortex Standard Silver Aluminum Rear Sprocket is a proven performer both on and off road, CNC machined from 7075 aluminum for amazing strength and light weight. That combination of light rotating mass and rugged construction translates into snappier acceleration and more predictable handling compared to a heavier steel OEM sprocket. AMA Superbike and Motocross riders trust the proven design of the Standard Vortex Aluminum Sprocket because of its tight tolerances and unique tooth design. That tooth profile is engineered to work smoothly with your chain for longer service life and quieter, more efficient power transfer, and it's why Vortex sprockets have become a fixture in winner's circles across multiple disciplines.

Finished in a clean silver anodized look, this 43-tooth, 525-pitch sprocket bolts on as a direct fit for compatible Yamaha models, letting you dial in your final drive gearing with a part that's built to Vortex's exacting racing standards rather than a generic aftermarket stand-in. Whether you're chasing lap times or just want a lighter, better-performing replacement for your worn factory sprocket, this Vortex Standard sprocket gives you race-proven hardware backed by decades of competition heritage.
