At DMG Motorsports, we present the Vortex F5 Rear Sprocket (454K-41) — a 41-tooth, 520-pitch black hardcoat aluminum sprocket engineered for select Kawasaki models. Vortex sprockets are a favorite among racers and street riders alike who want to shed rotating weight without sacrificing durability. This F5 sprocket combines a patented tooth profile with a tough PTFE-infused black hardcoat finish, giving you a component that looks as good as it performs while standing up to the demands of hard riding and track use.

Vortex's F5 sprockets start life as premium 7075 aluminum billet, CNC-machined to tight tolerances for consistent fitment and long service life. The black hardcoat treatment not only delivers a stealthy, aggressive look but also adds a layer of protection against wear, while the PTFE coating keeps the chain running smoother for longer. Compared to a heavier OEM steel sprocket, this aluminum design cuts rotating mass, which helps sharpen acceleration and handling — a difference riders can feel every time they twist the throttle.

Features:

• CNC machined from 7075 aluminum for amazing strength and light weight
• Hard anodized with a jet black dye
• PTFE coated for added lubricity and durability
• Unique tooth design increases sprocket longevity
• Aluminum construction is much lighter compared to an OEM steel sprocket, reducing rotating mass for improved acceleration and handling
• 100% CNC manufactured in the U.S.A.
• 41-tooth, 520-pitch design for select Kawasaki motorcycle applications
• Trusted by champions
