Vortex 525CZK-47 Black 47-Tooth 525-Pitch Aluminum Rear Sprocket

The Vortex 525CZK-47 is a 47-tooth, 525-pitch aluminum rear sprocket finished in black anodize, designed for street and sport motorcycle applications. Manufactured 100% in the USA, this sprocket is CNC-machined from lightweight CAT5 aluminum and engineered to deliver precise power transfer with reduced rotational mass compared to OEM steel sprockets.

• 100% USA manufactured — made by Vortex Racing, a U.S.-based company with decades of motorsport heritage
• Drilled lightening holes on most applications for additional weight savings
• Teeth hardened for increased wear life and durability
