Few things can take the enjoyment out of a great ride like numb, tingling fingers. The Kuryakyn 6339 grip end weights provide a higher level of comfort than when grips are used alone. Easily installed to the grip, ends add mass and length to further reduce high-amplitude handlebar vibration. Sculpted appearance and gloss black finish also add a high-tech look to your already hot-looking grips. Includes (2) gloss black bar end weights, (1) hardware kit including: (8) #4-40 x 9/16" socket head cap screw and (8) #4-40 x 3/4" socket head cap screw; suggested for installation (not included): set of hex wrenches. The Kuryakyn 6339 grip end weights are multi-fit and compatible with all Kuryakyn ISO grips, ISO flame grips, Spear grips, and Kinetic grips.
