Re: Rubber mounted handle bars?
One of those Girvin suspension stems may help. There are always a few on EBay.
Handlebars need to be attached very securely for safety reasons, so I would be afraid to rubber mount them.
I really dig that jolt and vibration in the bars when the engine starts, but my hands get numb on longer rides. Cheers
