Vortex 144-65 Silver 65-Tooth Rear Sprocket 525 Chain Stunt Sprocket

The Vortex 144-65 is a silver, 65-tooth aluminum rear sprocket designed for 525-pitch chain applications. Purpose-built for stunt riders and performance-focused motorcyclists, this large-diameter sprocket delivers dramatically increased low-end torque and the aggressive gear ratio needed for controlled wheelies and stunt maneuvers.

Key Features:

• 65-tooth stunt sprocket — ideal for stunt riding and maximum low-end pull
• 525 chain pitch — compatible with OEM 525 drivetrain applications
• Machined from 7075 aircraft-grade aluminum for exceptional strength-to-weight ratio
• 100% CNC precision machined for consistent fitment and balance
• Vortex patented tooth design increases sprocket longevity and reduces wear
• Silver anodized finish with clear coating to resist oxidation and corrosion
• Distinctive two-tone machined look — anodize applied before cutting exposes raw aluminum on tooth faces
• Reduces rotating mass compared to OEM steel sprockets for improved throttle response

Vortex recommends cleaning and tensioning the chain every 300–400 miles when running aluminum sprockets to maximize service life. The 144-65 is part of Vortex's extensive rear sprocket lineup, available for most sportbike applications.
