At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 40T-530 in Black Aluminum (527ZK-40) — a purpose-built race sprocket designed for select Suzuki and Triumph models running a 530 chain. This sprocket isn't just another OEM replacement; it's a lightweight, race-proven upgrade that shaves rotating mass while adding a serious dose of style to your drivetrain. Vortex sprockets are trusted by champions on the track, and this CAT5 series piece brings that same performance pedigree straight to your bike.

Every CAT5 sprocket starts life as a billet of premium material that is anodized in color first, then precision CNC machined, exposing bright silver highlights across the finished surface for a look that stands out even when the bike is parked. Beyond the aesthetics, the reduced rotating mass of an aluminum sprocket versus a stock steel unit helps improve acceleration and handling, while Vortex's proprietary tooth geometry is engineered to extend chain and sprocket life under hard use.

Features:

• Anodized FIRST, then CNC machined from 7075 aluminum for a striking black finish with bright silver highlights
• 40-tooth, 530-pitch configuration designed to fit select Suzuki and Triumph applications
• Unique, patented Vortex tooth design that increases sprocket longevity and chain life
• Lightweight aluminum construction reduces rotating mass for quicker acceleration and sharper handling versus heavier OEM steel sprockets
• 100% CNC manufactured to tight tolerances for consistent, reliable performance
• Race-proven design trusted by champions on the track
• Direct bolt-on replacement for a clean, factory-style fit
