I purchased these handle bar grips a couple weeks ago. I would say that these are a lot better then the stock grips. I put them on before i would ride hard in the sand dunes for a week. When i got back i didnt notice any wear in them. Shipping from this site is extremely fast! i got them before the date it said it would be at my doorstep! I would purchess other accessories from this site. The grips move a little bit but i think thats because of what grip stick i used.
