I have used an assortment of grips, and they are all different. It depends on preference, but I prefer smoother grips that are a bit softer. The stock grips for some reason always tend to grip into my hands excellent, but leave callases (which I dont mind, I grew up on a farm throwing hay and stuff, but when they are the liquid kind and pop, it sucks huge especially when getting muddy and stuff). I am using these on the xx http://www.rockymountainatvmc.com/p...lebars-Control&webCatId=12&prodFamilyId=17906. They are pretty comfy and soft. The stock ones always have the squares in them, which is what causes my problems. It is something I can tolerate, but comfort for a few bucks to me is worth it.I've never used any aftermarket grips because I never had any trouble with the stock ones. Is there a huge difference in comfort?
