ISO grips are the goods. I switched because I put different handlebars on my bike and the end caps wouldn't go on the new bars with the oem grips. They are larger in diameter, so I guess that could be a problem if you have tiny hands. Installing was a royal pain, lot of sand paper before I could get the throttle side to fit. It's true that everyone and his brother has these grips, but that just means they're good.
