I have had a 2004 Gold Wing and a 2009 Royal Star Venture. Both have a wrap around trunk/backrest for the passenger and "grips" for them on each side of the seat. My wife and I went for a ride yesterday up some of the canyons around here and she felt "very exposed". Is there something I can put on the bike to help her feel more secure in the seat? I have already suggested bungie and duct tape. No go.
