MSRP: $70.95

$51.95$73.95

Description

Vortex Racing has been manufacturing championship winning sprockets since 1995.  Their race proven CNC machined aluminum sprockets are made from the highest strength 7075 aircraft grade aluminum and have become the industry standard for light weight, high strength sprockets.

Vortex rear sprockets are available in 7075 high strength aircraft grade aluminum and steel.  Aluminum sprockets are lighter weight and preferred when performance counts.  Read here about improving handling and horsepower by removing unsprung rotating mass from a motorcycle.

Eletro-plated black steel sprockets are more durable and will last longer if you are racking up the miles commuting to work.

Aluminum sprockets are available with type 2 anodize in black, blue, red, or natural aluminum.  Vortex also offers their aluminum rear sprockets in F5 Hardcoat.  The F5 PTFE Black Hardcoat is built for endurance.  After type 3 hard anodizing with a jet black dye, they then coat the sprocket with PTFE (Teflon type material) for added lubricity.  The result is an ultra tough, ultra light sprocket that stays cleaner and lasts longer.
