How about these ? I put them on all my bikes, as most oem grips feel like you are trying to twist a pencil. Too skinny for my size hands. These have some cushion to them and a larger contour to them. $12.00 usd from vintage750. Gran Tourismo.
I really like my Oury grips. A bit larger in diameter and softer than the originals. Oury Grips - Handlebar Grips | Lizard Skins Plus I like how they look, even ordered up a pair for my bicycle.
