"Air Ride For Your Hands!" The Avon Air Cushion Chrome grips feel great and are very functional too. Manufactured in the USA with a special core bar that creates air pockets inside the grip body. These air pockets dampen vibrations, help eliminate the tingle in your hands and soften the overall feel of the ride. The soft serrated texture on the grip surface helps you hold on to your bike with no-slip confidence. The grips are finished off with only the best - 6061 billet aluminum gatlin end caps and collars. Fits HD Push Pull & Fly By Wire. Inside length = 4.600" OD = 1.625". We have worked hard to create the best feeling V-Twin grips for both warm and cold riding conditions. Sold in pairs.
