At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket, 42T-520, in a striking Black finish, engineered as a direct-fit upgrade for select Suzuki and Triumph models (Part No. 526AZK-42). This isn't just a bolt-on replacement for your tired OEM steel sprocket — it's a race-proven component built to shed rotational weight while adding serious visual attitude to your rear wheel. Vortex has spent years perfecting the CAT5 line, and this sprocket carries that legacy of performance and craftsmanship into every tooth.

What sets the CAT5 apart is its distinctive manufacturing process: anodized first, then CNC machined from 7075 aluminum. The Vortex CAT5 Series Rear Sprockets are anodized in color FIRST then CNC machined from 7075 aluminum to produce a trick colored sprocket with silver highlights. The result is a bold black finish with contrasting silver machined highlights that looks as aggressive parked as it does at speed. Beyond the looks, this sprocket delivers real performance benefits. An aluminum sprocket is much lighter compared to OEM steel sprockets and this leads to reduced rotating mass and allows for improved acceleration and handling. The tooth profile itself is purpose-built for durability, featuring saber tooth grooves; unique tooth design increases sprocket longevity.

This 42-tooth, 520-pitch sprocket is designed to fit a wide range of Suzuki GSX-R600/750/1000, SV1000/1000S, and GSX-S750 models, as well as Triumph Bonneville, Daytona, Scrambler, Speedmaster, Thruxton, Tiger, and TT600 models — check your specific year and model for exact fitment. Whether you're chasing lap times or just want your bike to look and feel sharper, this Vortex CAT5 sprocket delivers the trusted quality that has made Vortex a favorite among racers and enthusiasts alike.
