At DMG Motorsports, we present the Vortex F5 Rear Sprocket 42T-520 Black HC (452AK-42), a championship-proven, race-ready sprocket built for Kawasaki models running 520 chain conversions. Vortex has long been a favorite among racers who demand precision-built components that shed weight without sacrificing durability, and this F5 sprocket delivers exactly that. Whether you're chasing lap times on the track or simply want a stronger, lighter, better-looking replacement for your stock steel sprocket, this Vortex F5 gives you a direct upgrade in both performance and style.

This sprocket is CNC machined from 7075 aluminum for an ideal balance of strength and light weight, then hard anodized with a jet black dye and finished with a PTFE coating that adds lubricity and extends service life. The Vortex F5 Aluminum Sprocket is 100% CNC-machined and features a PTFE black hard-coat for increased wear resistance, with each sprocket machined from 7075 T6 aluminum to a very high tolerance. Its unique tooth design increases sprocket longevity, and the Vortex patented sprocket design is unlike any other sprocket on the market. Lighter rotating mass at the rear wheel means quicker acceleration and sharper handling compared to a heavier OEM steel sprocket, making this a smart upgrade for street or track use on compatible Kawasaki models.

Features:

• CNC machined from 7075 aluminum for outstanding strength and reduced rotating weight
• Hard anodized with a jet black dye for a sharp, aggressive finish
• PTFE (polytetrafluoroethylene) coated for added lubricity, corrosion resistance, and durability
