The Vortex 817ZK-48 is a CAT5 aluminum rear sprocket featuring 48 teeth in a black anodized finish. Engineered for serious riders and racers, this sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy to Vortex's exacting specifications, delivering a precision-machined component with exceptional concentricity and durability.

Key Features:

• 48-Tooth CAT5 Aluminum Construction — Lightweight aerospace-grade alloy reduces rotating mass for improved throttle response and faster acceleration
• 100% CNC Machined in the USA — Tight manufacturing tolerances ensure a perfectly concentric sprocket and smooth, consistent power delivery
• Black Anodized Finish — Hard anodized black coating provides corrosion resistance and a clean, aggressive appearance
• Vortex Patented Tooth Design — Unique tooth profile increases sprocket longevity and reduces chain wear
• Debris-Clearing Grooves — Tooth grooves help evacuate dirt and debris to keep the drivetrain running cleanly
• Lightening Holes — Strategically placed cutouts further reduce unsprung rotational mass without compromising structural integrity

The Vortex 817ZK-48 is the preferred choice of racers and performance street riders looking to optimize gearing, shed drivetrain weight, and improve overall motorcycle performance. Always ensure the chain pitch and sprocket bolt pattern are confirmed for your specific application before installation.
