If you have small hands you may not like them, better off getting new grips, the Grip Puppies make the grips much bigger around, I have average sized hands and they fit me well.
That is very true. I had them on my V-Strom on top of the heated grips, they were very comfortable, but borderline too thick for someone with medium sized hands like me.
I put them on my wife's Rebel, right over grip heaters wrapped on the stock grips. It helps eliminate some of the vibration. For $7-$8 a pair, can't go wrong.
I have an extra set of grip puppies for one inch bars, I got them thinking that they would fit, but never took them back. If anyone wants a set of one inch grip puppies, PM me. They will not fit stock 7/8 grips, though.
