I have ISO grips on my Goldwing. I like the throttle boss but the grips are a bit on the thick side. I've had the foam type grips on a couple of other bikes but they don't last very long before they deteriorate. I find the OEM grips on the SW comfortable and they don't cause me pain at the base of my right thumb so I'm considering replacing my ISO grips on the GW back to OEM style. One irritation with the Kuryakyn ISO grips is the chrome began to wear off after about three years use. At the price of those things the chrome ought to last.
