All the power your machine makes, goes through this flange. So make sure you have the best.

Your stock OEM sprocket hub is large and heavy... it's a six-armed steel flange of 7 3/16" diameter. The large diameter creates a "flywheel" effect which means that a certain amount of power is required just to affect the rotation of the flange. In other words, acceleration and deceleration of the axle assembly is slower (less responsive) than it would be without the flange. The design goal of the Durablue flange is to lessen this "flywheel" effect. To do so, high strength aluminum is used for the flange section. You will lessen the total weight and enjoy a more responsive ride.
Honda If your aluminum sprocket hub does not provide the service and reliability you need, our STEEL sprocket hub is the performance answer.
