Passing thru BC, YK to Fairbanks - bring motorcycle or not?

Thanks Soup. Had an inreach many years. We do a lot of offloading, only used it twice, once came upon injured riders, 2nd time someone broke down?? hope to keep it that way. Seems bike may be a bigger hassle. Jeep is good to go, no worries.

There are a zillion places to go ride. Even though I consider interior Alaska to be more buggy country.
If you already have the setup it’s not difficult to bring with.
Sounds like an awesome trip!

There are thousands and thousands of places you can take your bike, however you need to know where you can and can’t go. A lot of First Nations land won’t allow or have restrictions on who and what can travel on their land. You also need to be aware of active logging and mining roads. Most of theses roads with be posted with signs and are radio controlled to watch out for that.
Your Jeep will be great for exploring side roads all up and down BC and the Yukon.
If you really want to explore back roads get your self a few of theses off road books that show you what’s up the end of xxx road.
Theses books are called Back Road Map Book

I have a Side x Side and I use these books often for the area where I live in South eastern BC.

However, if your going to start taking off in the bush that you are unfamiliar with I would recommend getting a Garmin InReach GPS with 2 way texting and learn how to use it.
There are very very few communities when you start up Hwy 37, and if you break down or get hurt in the bush no matter in the keep or on your bike you’re on your own, as there is no cell service that you can use to get help.
Don’t forget to stop at Stewart BC / Hyder Alaska, to view the bears and drive your keep up to the Salmon Glacier.
Have a blast on your trip.
Soup.

OK, so no major off road adventures requiring a dual sport?

Thanks

Roads that way are, in general, very sketchy due primarily to continual weather damage and permafrost heaving. Your RV will be jouncing along, as will the jeep. Less stress is less stress, but any experience is unique when done with a bike. :-)
Since (it sounds like) you haven't been before, I'd suggest enjoying it with the group and the other toys, and go back with the bike next time. It's amazing!
