The HD4’s reputation was defined by winning the overall team title in the Enduro World Series. Built for speed, it excels on steep terrain. While slaying the rowdiest descents may be expected of a world class enduro bike, sprinting back to the top is not. Thanks to the dw-link suspension design, cries of “That thing flies uphill” are common among the slack jawed first time riders.
