I'm running the stock handlebars on my XR650L. I'm trying to reduce vibration. I've seen several posts on this forum that offer suggestions. Expandable Foam Fasst Inserts BBs, birdshot, etc. Bar Snake (assuming epoxy) Replace with aluminum handlebars Fill bars with silicone Different Grips Change the way you grip the bars (don't hold on so tight) I like fixes that are removable (and cheap), so I started with BBs. Test 1: Filled a 6" long rubber tube with BBs, wrapped that with duct tape, and stuffed it into the throttle end of the handlebar. Result was very little change, if any. Test 2: Same as test 1, plus another tube on the clutch side. Result: no change. Test 3: Removed rubber tubes from tests 1 & 2. Filled the entire bars with BBs. Result: no improvement. Might have made things worse. And a few are still rolling around on the garage floor Bar snake and fast inserts are a bit expensive, and I have read mixed reviews. I'd rather spend my $ on new bars, if I knew it would work. The expandable foam idea seems good (and cheap), but it's non-reversible, so if it doesn't work, I'd need to buy new bars anyway. Would like to hear from anybody else that has done this. Does anybody know of something that really works, based on experience? The only thing that seems proven is to buy new bars. I understand that the bars are going to "shake", especially at low RPM, and that's OK. It's that higher frequency tingly/buzzy vibration that gets me.
