This DENALI Bar Clamp Light Mount Kit allows fitment of any DENALI LED Light Kit to inner fork tubes on motorcycles, or any tube 39 mm - 49 mm (1.6 - 1.875 inches) or 50 mm - 60 mm (2 - 2.375 inches) in diameter. These light mounts have a unique octagonal inner profile that allows the clamps to securely grip a wide range of tube diameters and include an optional, fully rotatable mounting shelf to create a super versatile and robust light mounting solution. The 50 mm - 60 mm (2 - 2.375 inches) clamps are intended for motorcycles with exposed inverted forks such as enduro, dual sport, and naked motorcycles. The clamps allow lights to be mounted in front of, or to each side of the fork tubes to ensure clearance with fairings and other accessories. The clamps are also perfectly sized to clamp to the lower legs of conventional forks, typically found on many cruiser and standard motorcycles. Adjustable grip range 39 mm - 49 mm or 50 mm - 60 mm.
