Renthal does list different diameter ones but are 125mm in length or 4.92 inches long. I have motion pro grips on my race bike and they fit perfect. Motion pro says their length is 4.8 inches long. Renthal list the G175 as 3 inches long....looks like you need this one. Renthal G149 Black Full Diamond Firm Compound Sportbike Grip, specs say 4.75 inches long
