Bought some squishy, sportbike grips and tried to change them out. Glad I didn't cut the originals off because I could NOT get the new grip on. 7/8", which seems to be the universal sportbike grip size. Harleys tend to be 1". Even with soapy water it was a no-go. Perhaps my snowflakedness is showing and i just need to get more elbow grease into it Or, maybe they are 1"
