At DMG Motorsports, we present the Vortex 527S-42 Steel Rear Sprocket — a 42-tooth, 530-pitch black rear sprocket engineered for select Suzuki and Triumph models that demand durability without sacrificing performance. Vortex has spent years building race-proven drivetrain components, and this steel rear sprocket carries that same reputation for tight tolerances and long service life onto the street and track alike. Finished in a satin black electroplating, it not only resists corrosion but also gives your bike's rear end a clean, blacked-out look that pairs perfectly with an aftermarket chain and front sprocket.

Built from high tensile carbon steel and precision CNC machined to exacting standards, this sprocket is designed to handle the abuse of daily riding and spirited runs alike. Vortex's signature Ideal Tooth Design™ ensures the chain engages and releases smoothly with every rotation, reducing wear on both the sprocket and your chain over time. Whether you're replacing a worn OEM sprocket or upgrading for improved durability, the Vortex 527S-42 is a proven, direct-fit solution backed by a brand trusted by racers and enthusiasts alike.

Features:

• Made of high tensile carbon steel and precision CNC machined individually for tightest tolerances
• Ideal Tooth Design™ for perfect chain hold and release with maximum wear resistance
• Electro-plated satin black finish resists corrosion, and hardened teeth ensure the sprocket holds up to many miles without affecting strength
• Cupped down from the tooth ring to the body to reduce as much weight as possible
• 42-tooth, 530-pitch configuration designed as a direct-fit option for compatible Suzuki and Triumph motorcycles
• Unique tooth design increases sprocket longevity thanks to Vortex's patented sprocket design, unlike any other sprocket
