As a Semi-professional rider I would suggest, either the Suzuki 650SV or the Kawasaki KLR650. The SV is more street oriented but with a bashplate installed is certainly capable of decent gravel road performance. It is NOT capable of OFFRoad riding.
The kawasaki KLR is a twenty something year old proven design(once the Dohicky is fixed). It is a true enduro, capable of half decent on road speed and good gravel road performance(with the right tires)(and it's ugly). It is also capable of some Offroad use(you can drag it out of swamps,sandpits,rivers,etc).
A decent KLR can be had for $3500 an SV is $5000.
I would go with KlR for Yukon riding and the SV if you were going to travel south for any considerable distance.They are both capable of hauling passengers with "some" degree of comfort.
Good luck, Peter
