Howdy fellow H-D enthusiasts ! Without going into details, a group of 17 bikes met to go on a ride this past Saturday. ( Great weather for a ride ! ) At the first red-light, several of the tail end bikes were cut off from the group, and because lights were timed, were never able to catch up to the group until we hit our destination. We've been kicking around ideas of how to countermeasure another separation, and are talking about getting communication device that the ride captain and a "tail-gunner" could communicate such issues. Not wanting to establish one rider as a tail-gunner ( fixed helmet comms ) I'm wondering if anyone can recommend head-set communications devices that could be shared? It would need to fit in various helmets ( no helmet ), and probably be battery powered, or capable of being powered by an H-D aux. plug. Any suggestions? Thanks in advance for the help!
