At DMG Motorsports, we present the Vortex Front CS Sprocket Steel 15T-520 (Part# 3481-15) — a precision-engineered countershaft sprocket built for select Suzuki models running a 520 chain conversion. Vortex has spent decades supplying racers and street riders alike with top-quality drivetrain components, and this front sprocket is manufactured to the same exacting standards that have made the brand a trusted name in motorcycle gearing. Whether you're upgrading for durability, quieter operation, or simply replacing a worn OEM sprocket, this steel 15-tooth unit delivers reliable power transfer and long-term performance.

Built from durable steel and finished with a corrosion-resistant zinc coating, this sprocket is precision manufactured and induction hardened to precise tolerances, improving concentricity for a stronger, quieter, and longer-lasting ride. Drilled lightening holes help reduce rotating mass, contributing to snappier acceleration and reduced drivetrain inertia — a hallmark of Vortex's engineering approach across their sprocket lineup.
