Hi STB,
I made the leap to a demo '17 SR about a week ago. I also use my bike as my full time transportation. I've been commuting year-round since '89. This is my 33rd bike since 1980. First, their offer is pretty good. I got mine for about $4k off but that was after quite a bit of haggling so I think you've squeezed about all you'll get out of them. My wife of 28 years gave up long ago trying to keep up with my bike purchases. Usually she notices when I leave on one bike and come home on a different one (although once it took 2 days because the bikes were the same color). We came to an agreement that as long as the net costs don't affect the family budget, I could buy whatever I wanted.
When calculating net cost, be sure to highlight the vastly reduced maintenance costs and refueling savings. Have you paired your smartphone to the bike using the ZERO app? Plug in your home's cost per KW/h, MPG of your present bike (or her car), and the local cost of a gallon of gas (my bike required mid-grade). If you can charge free at work, that's an additional boost in savings. The app will tell you how much you've saved and what your cost per mile is. Mine is $0.013 per mile and I've saved $44 in gas. My bike has 650 miles of which I contributed 450 of them. I would suggest you get the dealer to charge the bike overnight to get a full and balanced charge, Then take it on an endurance run to see how far you can go on a single charge riding the same roads and riding style as your daily commute. Use the data from that ride to come up with a baseline. Another major selling point I had was that I leave for work at 6am while she gets to sleep 2hrs later. When I was riding some previous bikes, the sound of the exhaust (looking at you Ducatis and Yamaha Roadliner) on start up would shake the walls and wake her (and the neighbors) up earlier than she wanted.
Depending on where you live, the onset of colder weather can drive down the value the bike you're selling faster than the thermometer. If possible, hold on to your Honda until spring when everyone gets the itch to ride again and used bike prices are at their max. I buy most of my used bikes in the window of time from 1 week before black Friday when people want cash for the "big sales" and 2nd week of Jan when the credit card bills from Christmas come due. Since folks "need" the money and see the bike sitting in the corner of the garage and know they won't ride it for another 4-5 months, they'll sell it for a song. I pick up those bikes for 1/2 of what they'll sell for in the spring.
