The Vortex 615-59 is a silver aluminum 59-tooth rear sprocket engineered for performance motorcycle applications. Designed and manufactured by Vortex Racing, this sprocket is built to deliver reliable power transfer while reducing unsprung weight compared to stock steel sprockets.

Key Features:

• 59-tooth rear sprocket for increased low-end torque and acceleration
• Vortex patented tooth profile design engineered to extend sprocket service life
• Silver finish with a clear protective coating to resist oxidation and corrosion
• Lightweight aluminum construction reduces unsprung rotational mass
• Precision CNC-machined for consistent fit and smooth chain engagement
• Part of the Vortex 615 series rear sprocket lineup

Vortex Racing is a trusted name in motorcycle drivetrain components, known for producing high-quality sprockets used on both street and track applications. The 615-59 sprocket must be paired with a chain of matching pitch — always verify chain pitch compatibility before installation. Sprocket and chain should be cleaned every 300–600 miles on street bikes to maximize drivetrain longevity.
