At DMG Motorsports, we present the Vortex Rear CAT5 Sprocket in Aluminum, 44-Tooth, 530 pitch, finished in Black for Yamaha applications (part #840ZK-44). Built for riders who demand less unsprung weight and more confidence off the line, this sprocket swaps out a heavy OEM steel unit for a lightweight, race-bred aluminum design that has powered champions on the track. The CAT5 series is instantly recognizable thanks to its process of anodizing the sprocket in color first, then CNC machining it to reveal sharp silver highlights against the black finish — a look that's as functional as it is aggressive.

Features:

• Anodized FIRST then CNC machined from 7075 aluminum
• You end up with a trick colored sprocket with silver highlights
• Saber tooth grooves; unique tooth design increases sprocket longevity
• 100% CNC manufactured in the U.S.A. from a specially formulated alloy per Vortex specifications
• Machined from lightweight aerospace-grade aluminum to be lighter and much more appealing than OEM steel sprockets
• Trusted by racing champions for its proven design, tight tolerances, and unique tooth pattern
• 44-Tooth count, 530 chain pitch, Black finish — designed for Yamaha applications
• Trusted by champions in road racing and track-day competition
