Black, for 7/8 inch handlebars. The knurled bands encircling this timeless design have been scientifically calculated to allow the proper channeling of sweat from your palms equally well when whiteknuckling around the track or putting along through the desert, all the while providing you with the security and style that one desires from a motorcycle handgrip. Basically, this is a great looking grip that performs great and is at home on any make or style of custom motorcycle. The alternating bands of diamond knurling and smooth are aestheically pleasing while giving a solid, comfortable grip on these injection-molded Krayton rubber handlebar grips. It is important to choose the proper size grips for your motorcycle. Grips are available in 1 inch (the size needed for all Harley-Davidsons and other 'cruiser' style motorcycles) as well as 7/8 inch (common on many vintage British, European and Japanese motorcycles such as Triumph, Honda and Yamaha). Please note that any pair of motorcycle grips has two different inside diameters. The grip for the left side (as if you were sitting on the bike) of the handlebar has a smaller diameter, and the right side grip has a larger inside diameter to fit over your throttle tube. Grips are manufactured to have a tight fit, you don't want one sliding off while taking a corner or twisting the throttle! They are easy to install using a bit of WD-40 to help get them in place.
