I was looking at an STR 1300 myself. My previous bike was a GSX 1100G that the wife refused to get on.
The STR 1300 would be great as a solo rider, but 2 up long distances would be a challenge.
The wife sure likes her comfy couch on the wing complete with her own a$$ warmer.
I think the comparison is apples to oranges. The STR is a sport touring bike for short and medium distances. Having test drove one for a 100 km trek up in Northern ontario canada, I can't see myself doing a cannonball 22 hour run like I just did on my wing.
But each to their own
Well, my wife and I just rode our ST1300 two-up with camping gear from Washington State across the country to Nova Scotia (The Cabot Trail) and Quebec (The Gaspe' Peninsula) and back.... 8,910 miles....Idaho, Montana, North Dakota, Minnesota, Michigan, a slice of Ontario, New York, Vermont, New Hampshire, Maine, New Brunswick, Nova Scotia, Prince Edward Island, Quebec, and the rest of Ontario....and back again.....
Gee, I didn't know we couldn't do that!
I believe the artificially set limits on bikes -- "that's a touring bike, that's a sport bike, that's a trailer-bike" -
- are all patent nonsense. The world has been circumnavigated by people on 50 ccs, and by a double amputee on a junkyard Harley (Dave Barr). My advice to all is to disregard "expert" advice, and do what you want with what you got....... but, as the man says, to each his own......
