I can see where a V7 or V85 will be a little below what many today feel is "ample power" for two up, with luggage, touring, especially at higher speeds and altitude. If this is where and how you ride, and you want a new Guzzi, choose a V100 Stelvio or Mandello.
I don't ride two-up much, and never 2-up on long rides loaded down, but Barb and I would do just fine touring on my V85. There's plenty of room, she doesn't enjoy riding aggressive or going very fast, and we'd be almost entirely on 2-lane 50-60 mph roads anyway.
Almost 55 years ago I was just getting into motorcycles and although I was saving for a new Honda 250 I was envious of what "real riders" passing through were riding like Harley Shovelhead dressers. There were riders who had been touring all over the country, many 2-up, with gear, on 30hp R60/2s and R75/5's. I loved visiting the BMW shop and recall talking with a couple who had traded up to an R90, they said "these have all the power anyone could ever use". I dreamed of owning that motorcycle but they were so big and selling for almost $3,000 back in 1973 it wasn't realistic to even dream about it, heck I was working hard to save $850 for the new XL250.
It's just interesting thinking a V85TT has about the same power as an R90, maybe a bit more, but some consider them "nice motorcycles just a little under powered". An R90 or V85 can run 2-up on 70-75 mph Interstate Highways with traffic that is moving at 80-85 mph but that's about it, without much in reserve, and it's not where it's happy. If you do this type of riding there are many better choices.
