A handlebar vibration damping assembly (HVDA) (10) that is used in combination with a conventional two-wheeled vehicle's handlebar (80) assembly having a right grip (82), a left grip (84) and a center section (86). The HVDA (10) is comprised of a weight (12) having a first end (14), a second end (16), an outer surface (18) and a cavity (20) that extends into the second end (16). A spring (22) has a first end (24) and a second end (26), with the first end (24) inserted into the cavity (20) on the weight's second end (16). In order to maintain the HVDA (10) within the handlebar, a bolt (32) having a head (34) and a tip (36) along with an insert (38) having a bore (40), an insert nut (44) and a second nut (48) are utilized. The second end (26) of the spring (22) extends into the insert bore (40). Once the HVDA (10) is securely placed within the handlebar (80) the weight (12) can vibrate in any excitable direction 90-degrees of the centerline of the handlebar and can oscillate at different frequencies.
