I have the Avon Air Cushion grips with Throttle Assist and they are great. Much better than what the bike came with. Your hands don't tire so much and the bigger diameter makes them more comfortable.

I ride a Softail Heritage and the grips dampen a lot of the vibration coming from the engine and from the windshield at higher speeds. Also, the grip is very good with and without gloves.

I have the chrome ones and after two years they still look like new. They also sell a large selection of grip ends to suit your taste. I should also mention that installation was very easy.

My wife really likes hers. If I change grips, I'd consider them too
