At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Black, a 44-tooth 520-pitch aluminum sprocket engineered specifically for Yamaha applications (part# 840AZK-44). Vortex has built its reputation on the track, and the CAT5 line carries that pedigree straight to your bike with a design that's as striking as it is functional. Rather than machining a colored sprocket, Vortex anodizes the piece first and then CNC machines it from 7075 aluminum, so the finished sprocket shows off bold silver highlights against the black anodized surface for a genuinely custom look. Backed by Vortex's unique tooth geometry and race-proven reputation, this sprocket is a smart upgrade for riders who want reduced rotating weight without sacrificing durability on the street or track.

Features:

• Anodized first, then CNC machined from 7075 aluminum for a distinct two-tone finish
• Bold black anodized coloring with contrasting silver machine-cut highlights
• Unique tooth design that increases sprocket longevity and improves chain engagement
• Lightweight aluminum construction to reduce unsprung and rotating mass versus OEM steel sprockets
• 44-tooth, 520-pitch configuration designed for Yamaha fitments
• Vortex's patented sprocket design, trusted by champions in professional racing
• Precision manufactured to Vortex's specially formulated alloy specifications
