For the record, I'm the dude with the V-Strom stuck in the ocean. The reason it's not covered in mud is because I hit quicksand and the bike sank really deep really quickly.
I did this ride, to Inuvik, a couple of years ago. I think it's an amazing idea, and you should absolutely do it. However, you are straight up out of your mind if you think you can do it in the timeframe you've outlined. I have a fair amount of long distance riding experience, and I'm known to hustle and to do long days. Take my opinion for what it's worth, but I have some experience you may want to take advantage of.
Firstly, your highest mileage day will always be your first. You're excited, you're fresh, nothing's gone wrong and from that point on it becomes straight up a lot of work to get miles in. And miles make you tired. Tired leads to mistakes. Mistakes lead to problems and potentially injuries.
Next, the chances of you being able to do all of this on one set of tires safely is small. What are you going to do for tires? My recco - plan ahead and have a set of tires waiting for you. When you get into the wilderness, you can no longer count on parts being available. And sometimes it means waiting a week or longer for things to come in.
Are you camping? If you are not bringing any camping equipment, you need to have reservations as soon as you start heading north. The tourist travel season is very short in the north, and most towns do not have a lot of rooms, and those rooms fill up quickly especially on the weekend. On several occasions when I wanted a room I was forced to camp because there were no rooms anywhere. They're also spectacularly expensive. Supply and demand...
The Dempster demands your respect. If you do your research you'll see how quickly the weather changes, and how bad the road gets when it's wet. The calcium chloride that they use to harden the road in the dry turns to "pig snot" as the locals say and it's downright hazardous to bikes. The Dempster may be in such bad condition the day you're there that doing it would be a bad idea. Having the ability to wait a day or so if you can for conditions to improve would be a smart idea. The D is not just a dirt road, it's a living thing that goes from beautiful hardpack to 3 inches of powder sand to ruts to ridges to grease, most of the time without warning, all at highway speeds.
The Dempster, and potentially other roads depending on your bike's range, will dictate that you carry gas with you for parts of the trip.
Happy to answer any questions you have, and I'm not trying to deter you - just to give you some things to think about as you plan for this. It's an amazing trip and you should make it happen.
There is so much to see and do on this route that never getting off the bike is a waste. And trust me, after 5 days or so of blitzing, you're going to be so tired you'll want to stop and smell the roses a bit. Not having lots of pictures from a trip like this would be a shame.
