Vortex 526AS-45 Steel Rear Sprocket 520 Pitch 45 Tooth Black

The Vortex 526AS-45 is a high-performance steel rear sprocket designed for sportbike enthusiasts seeking durability and weight savings. Manufactured from premium carbon steel with an electroplated satin black finish, this 45-tooth, 520-pitch sprocket delivers exceptional wear resistance and corrosion protection for long-lasting performance.

Key Features:

• Premium carbon steel construction for maximum strength and durability
• 45 teeth with 520 pitch configuration
• Heat-treated tooth surfaces for extended service life
• Electroplated satin black finish resists corrosion and looks great
• Cupped design reduces weight without sacrificing strength
• Precision-machined for smooth, quiet operation

This sprocket is designed for chain conversion applications, allowing riders to upgrade from heavier 525 or 530 chains to the lighter, more efficient 520 pitch. The heat-hardened teeth maintain precise geometry through thousands of miles of use, while the cupped profile strategically removes material from the sprocket body to minimize rotational mass. The satin black finish not only provides superior corrosion resistance but also complements modern sportbike aesthetics.

Note: This sprocket is intended for use with 520-pitch chains and is commonly used for chain conversion applications on motorcycles originally equipped with 525 or 530 pitch chains.
