The Queen's Throne on the back of my Ultra. She has carpal tunnel and her hand goes numb in seconds on the throttle. That's why we got the Ultra, now we're both happy and comfy.
My wife is finally riding on the back of my RK. She just started riding with me a couple months ago on my 05 1200 Custom - shortly there after I ended up with an 08 RK. Go figure. Everyone still thinks she'll want her own bike in a year or two. We'll see.
My wife rides a 2008 Street Glide. Before that she had a 2006 Street Glide. Before that a 2004 1200 Sportster. Before that a 750 Yamaha Virago and my 89 Springer. She puts on about 12000 a year. Thing is she never even rode a bicycle when she was a kid.
