Vortex 206ZL-42 Aluminum Rear Sprocket 420 Pitch 42-Tooth

The Vortex 206ZL-42 is a lightweight, high-performance aluminum rear sprocket designed for 420-pitch chain applications. CNC machined from aerospace-grade 7075-T6 aluminum, this 42-tooth sprocket offers exceptional strength while significantly reducing rotating mass compared to stock steel sprockets.

Key Features:

• CNC machined from 7075-T6 aluminum for optimal strength-to-weight ratio
• 420 chain pitch with 42 teeth for precise gearing options
• Patented Vortex tooth design increases sprocket longevity and reduces friction
• Color anodized finish prevents corrosion and adds distinctive style
• Lightening holes reduce rotating mass for improved acceleration
• Precision manufacturing ensures perfect concentricity for extended chain life
• 100% CNC manufactured in the USA to tight tolerances

Reducing rotating mass on your drivetrain components has a multiplied effect on performance. The weight savings from this aluminum sprocket improves acceleration and reduces wear on suspension components. Vortex's unique tooth profile design minimizes drag and friction for better power transfer and deceleration. Commonly used on Honda Grom and other mini bike applications requiring 420-pitch chain systems.
