Vortex 190-59 420 Aluminum Rear Sprocket 59 Tooth Silver

The Vortex 190-59 is a 59-tooth, 420-pitch aluminum rear sprocket engineered for powersports and mini bike applications. Manufactured to precise specifications, this sprocket delivers the concentricity and durability demanded by performance riders and racers alike.

Key Features:

• 420 Chain Pitch — compatible with standard 420-pitch drive chains used on mini bikes and small-displacement motorcycles
• 59 Teeth — higher tooth count tuned for increased low-end torque and acceleration
• Precision Aluminum Construction — made from a specially formulated alloy per Vortex specifications for strength without excess weight
• Lightening Holes — strategically placed to reduce rotating mass and improve throttle response
• Unique Tooth Design — increases sprocket longevity and promotes even chain wear
• Silver Anodized Finish — corrosion-resistant anodizing protects the sprocket and maintains appearance over time

The Vortex 190-59 rear sprocket is a direct-fit, high-performance upgrade over heavier OEM steel sprockets, reducing unsprung rotating weight for improved handling and acceleration response.
