At DMG Motorsports, we present the Vortex Front CS Sprocket Steel 17T-520 (3289-17) — a race-proven replacement sprocket engineered for Yamaha models like the YZF-R1 and FZS1000/FZ1. Vortex Racing has spent decades supplying top-tier drivetrain components to racers and enthusiasts, and this 17-tooth, 520-pitch front sprocket delivers the same OEM-level fit, strength, and reliability you expect from your final drive setup. Whether you're restoring stock gearing or dialing in your ratio for the track or street, this sprocket is built to handle the abuse of hard acceleration and high RPM shifts without missing a beat.

Features:

• Precision manufactured and induction hardened to precise tolerances for improved concentricity and a stronger, quieter, longer-lasting sprocket
• Zinc coated to resist corrosion and extend service life
• Drilled lightening holes to reduce rotating mass for snappier acceleration
• 17-tooth, 520-pitch design engineered as a direct fit for compatible Yamaha models
• Made from high-strength steel for durability under demanding riding conditions
• Backed by Vortex Racing's reputation for tight tolerances and top-quality materials used in professional racing
