At DMG Motorsports, we present the Vortex F5 Rear Sprocket 42T-520 Black Hardcoat Aluminum (436K-42) — a race-bred, championship-proven sprocket engineered to deliver the perfect balance of strength, light weight, and durability for your Kawasaki or Suzuki. Vortex takes performance seriously, and the F5 series is the result of decades of racing experience distilled into a drop-in upgrade for riders who demand consistent power transfer lap after lap, ride after ride. Whether you're chasing lap times on the track or just want a sprocket that will outlast the competition on the street, this Vortex F5 sprocket is built to perform.

Each F5 sprocket is precision CNC machined and then hard anodized with a jet black dye before receiving a PTFE topcoat, giving it a durable, low-friction black finish that resists wear far better than a standard anodized sprocket. The result is a sprocket that looks as aggressive as it performs, holding up to the demands of aggressive acceleration, hard braking, and repeated gear changes.

Features:

• CNC machined from 7075 aluminum for amazing strength and light weight
• Hard anodized with a jet black dye for a durable, aggressive black finish
• PTFE coated for added lubricity and increased wear resistance
• Unique tooth design engineered to increase sprocket longevity
• Trusted by champions and proven in real racing conditions
• 42-tooth, 520-pitch configuration designed to fit select Kawasaki and Suzuki models
