I see you made up your mind and that's good. There is nothing wrong with staying with one bike for awhile, at least until you get your money's worth.
I've been riding for 45 years now and have had a number of bikes over those years. Back in 1987, after crashing my '83 Honda 650 Nighthawk, I went to the VF700/V45 Sabres for 16 years (three different ones). When I got a bug to upgrade, my brother Dave and I discussed the ST1100 and the V65 Sabres. We decided that the V65 Sabres had more get up and go than the ST1100 did, so in 2003 we both bought V65 Sabres. That lasted all of two years, in October 2005 Dave went out and bought a ST1300. At first I told him he was nuts, but he had me looking at them within a month. So in November of 2005 I also had a ST1300.
By 2007, I had sold both of my V45/V65 Sabres and solely rode the ST1300. I put 174.3K miles on that bike before selling it to one of my sons In June of 2013. But by then I had a '04 and 2010 ST1300s. The idea was to use the '04 as my commuter and the '10 as my backup/long distance bike. I put 37K on the '04 before it was put in my shed, waiting for a waterpump, and in the meantime I had picked up another '04 and then last September, I bought a new 2012.
So now I have 4 ST1300s floating around. Both '04s need waterpumps (I'll get to those some day), my 2010 now has 48,600 miles on it (that I have put on) and my 2012 now has 2,200, (I'm commuting on it to get it ready for a 4,000 mile ride in less than two weeks).
I've had the '04 #2 up for sale (after putting 20K miles on it), but seems nobody wants to buy a good running ST1300 that has a salvage title and needs a waterpump. Oh darn, guess I'll just have to fix it and keep riding it too!
I found the bike that fits me, my riding style and comfort. I commute 125 miles a day and find the ST1300 is great for that because I can take extra gear for (cool/cold in the mornings and warm/hot in the afternoons) and still be able to enjoy riding it for long distances, like the ride Dave and I are doing to get to WeSTOC in Grand Junction Colorado.
When you find a bike that you like, why get rid of it just because Honda hasn't upgraded it or whatever? I find many, like my oldest son, they get bored and have to move on to something else. For me, I find something, I stick with it for as long as practical. The Mid 80's Sabres were great bikes, but parts were hard to find and they required a lot of maintenance to keep them running for what I needed. That's another reason the ST1300s are so great. You can get a lot of miles out of them before having to do much maintenance. Besides, now that I've been riding them for over 10.5 years and restoring three of them, I know these bikes very well, why would I want to change to something I would have to learn all over again?
Happy riding!
