Motorcycle sprockets

Athena presents a complete range of quality road and off-road chainwheels for the right maintenance of your two-wheeled vehicle.

Made of aluminum alloy, the Renthal chainwheels are ultralight, but at the same time extremely resistant.

The low weight and the considerable wear resistance obtained with the anodizing treatment make the Renthal rear sprocket the most used by professional riders. The chainrings are available in various colors and teeth, to meet your every need.
