Vortex 525-48 Steel Rear Sprocket Chain Pitch Sprockets - 48-Tooth 525

The Vortex 525-48 is a 48-tooth steel rear sprocket designed for use with 525-pitch drive chains. Manufactured in the USA by Vortex Racing, this sprocket is engineered to the tightest tolerances using premium-grade steel, delivering the durability and precision performance that Vortex is known for across road racing, motocross, and supercross applications.

Vortex rear sprockets are laser-cut from high-quality carbon steel and case-hardened for extended wear life. The teeth are specially hardened to resist wear under demanding riding conditions, and most applications feature drilled lightening holes to reduce rotational mass without sacrificing strength. An electroplated satin black finish provides corrosion resistance for long-lasting good looks.
