HFRA “Hyper Fast” 520 Conv Street kit with hardcoat aluminum rear sprocket. Gearing one down in front, two up in rear, SX3 Vortex Chain.

Vortex Steel Front Sprocket

• Drilled lightening holes reduce rotating mass
• High carbon steel for maximum strength
• Special Vortex Nichel plating to resist corrosion
• Induction hardened to reduce surface wear
• Precise tolerances to ensure concentricity

Vortex F5 Rear Sprocket

The F5 PTFE Black Hardcoat is built for endurance. After hard anodizing with a jet black dye, Vortex then coats the sprocket with PTFE for added lubricity. The result is an ultra tough, ultra light sprocket that stays cleaner and lasts longer. A Vortex sprocket is a lightweight high-performance alternative to the steel stock sprocket. Use Vortex sprockets to considerably reduce mass and to change your gearing. Made with highest quality aluminum.

• 7075 T6 aluminum is the best grade material for light weight and durability.
• The weight you save on drive components is multiplied as rotating mass.
• Less rotating weight improves acceleration.

Vortex SX3 Chain

• Drilled links reduce rotating mass
• X-ring seals to reduce friction
• Improved tensile strength
• Includes rivet type connecting link
