Vortex 190ZK-52 Black Aluminum Rear Sprocket 52-Tooth 428 Pitch

The Vortex 190ZK-52 is a 52-tooth, 428-pitch aluminum rear sprocket finished in a black anodized coating. Engineered for small-displacement motorcycles and scooters that use the 190-series bolt pattern, this sprocket is CNC machined in the USA from a specially formulated aluminum alloy to deliver a lightweight, performance-focused upgrade over heavier stock steel sprockets.

Key Features:

• 52-Tooth / 428 Pitch: Designed for 428 chain applications with a 52-tooth count for enhanced low-end torque and acceleration
• Lightweight Aluminum Construction: Reduces rotating mass compared to OEM steel sprockets, improving throttle response
• Black Anodized Finish: Durable anodized coating provides corrosion resistance and a clean, race-inspired appearance
• CNC Machined in the USA: Precision manufacturing ensures a perfectly concentric fit and smooth, consistent power delivery
• Unique Tooth Profile: Vortex's optimized tooth geometry extends sprocket and chain service life by reducing drivetrain wear
• 190-Series Bolt Pattern: Matches the specific hub and bolt-circle dimensions of compatible small-displacement models

The Vortex 190ZK-52 is a direct bolt-on replacement rear sprocket suitable for street and off-road riding. Always replace the drive chain when installing a new sprocket to ensure even wear and maximum drivetrain longevity.
