My wife and I went for a ride the other day on our 2006 Goldwing/Champion trike. When we got home and I was cleaning the bugs off, I noticed I was missing a handlebar damper off the throttle side. Could somebody please tell me if we really need these dampers on a trike, or can I take the one off the left side also, and put some caps in their place? I looked at some sites on the internet and it looks like they only sell the dampers in pairs. I didn't notice any end caps for them though. Thanks.
