At DMG Motorsports, we present the Vortex Standard Rear Sprocket in Aluminum, 42-Tooth, 520 Pitch, Silver finish (part number 526A-42) — a race-bred sprocket built for riders who demand less rotating weight without sacrificing durability. Vortex has long been regarded as the go-to name for aftermarket sprockets in roadracing and street performance circles, and this "Standard" model is the sprocket that set the bar for the rest of the industry to chase. Designed to bolt onto compatible Suzuki and Triumph platforms running a 520 chain conversion, this sprocket combines aircraft-grade aluminum construction with Vortex's signature tooth profile to deliver smoother power transfer, reduced unsprung mass, and a cleaner, more aggressive look at the rear wheel.

Features:

• Recognized as the "Standard" in the race industry, trusted across roadracing and street applications
• CNC machined from 7075 aluminum for an ideal balance of strength and light weight
• Unique, patented Vortex tooth design engineered to increase sprocket longevity and improve chain engagement
• Silver finish for a clean, race-ready appearance
• 520 chain pitch, 42-tooth count, built to fit select Suzuki and Triumph models
• Trusted by champions in professional competition
• Reduces rotating mass compared to heavier OEM steel sprockets, aiding acceleration and handling
