At DMG Motorsports, we present the Vortex Front CS Sprocket Steel 16T-525 (Honda/Triumph) — part number 2917-16 — a direct-fit replacement countershaft sprocket engineered to keep your drivetrain running smooth, quiet, and strong. Built by Vortex Racing, a name trusted for decades in Motocross, Supercross, Road Racing, and Superbike paddocks, this 16-tooth, 525-pitch steel sprocket is manufactured to tight tolerances for reliable, race-proven performance on the street or track. It's a proper fit for a range of Honda CBR600F/F4/F4i, CBR600RR, CBR900RR models as well as Triumph Sprint ST, Speedmaster, and Tiger 955i motorcycles, making it an easy upgrade or replacement for riders looking to restore or fine-tune their final drive.

Engineered with the same attention to detail found across the Vortex sprocket lineup, this CS sprocket is precision manufactured and induction hardened to precise tolerances, which improves concentricity and results in a sprocket that runs stronger, quieter, and lasts longer than typical stamped alternatives. A protective zinc coating stands up to road grime, moisture, and corrosion, while strategically drilled lightening holes shave rotating mass to help keep the drivetrain responsive without sacrificing strength.
