Simple and clean, these HD Factory Style Grips are black rubber and fit 1" bars. OEM #56206-81A. Please note that any pair of motorcycle grips has two different inside diameters. The grip for the left side (sitting on the bike) of the handlebar has a smaller 1" diameter, and the right side grip has a larger 1-1/8" 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!
