The Vortex 839A-48 is a lightweight aluminum rear sprocket featuring 48 teeth, designed for high-performance motorcycle applications. This precision-engineered component combines weight savings with durability for racing and performance street use.

Key Features:

• 100% CNC manufactured in the USA for precise tolerances and consistent quality
• Constructed from specially formulated aluminum alloy per Vortex specifications
• Silver anodized finish prevents corrosion and adds a clean, professional appearance
• Patented tooth design increases sprocket longevity and reduces wear
• Lightweight construction offers approximately 50% weight reduction compared to steel sprockets
• Two-tone machined look from coating applied before cutting

Vortex aluminum sprockets are ideal for road racing, motocross, flat track, drag racing, and performance street applications where weight savings are critical. To maximize service life, chain should be cleaned and properly tensioned every 300-400 miles. The unique Vortex tooth profile distributes chain load more evenly, extending both chain and sprocket life when properly maintained.
