No personal experience with this. By reading thru the 'reviews', it seems to incorporate elements of BOTH the most widely-suggested anti-vibe suggestions.You have or have not personal experience with this?
I bought kuryakyn sport bike grips at Dennis Kirk. They fit the 7/8 inch bars and are the right length for our bars. I always used them on cruisers as they are fatter and remove vibration. They work great for me and you don't need the bar end weights with them. Just say in'.I eliminated most of the buzziness in my handlebars by pouring BB's into the handlebar then I pumped a bit of silicone sealer into it to seal in the BB's. Seems to work. The only thing was that putting in the silicone sealer in was a bit messy and I used a lot of paper towels to clean things up.
