This is also early in the year for weather.
Dangerous goods is at worst $100.
I was told by the A/C rep that
All included, but DG paperwork is done outside our scope, so that’s separate. We are including the DG fee now though.

Dangerous goods ??
Truly - it's not a big deal to fly the bike the same time you leave for Van permanently.
There are however less expensive trucking options.

HOWEVER ......this may be a unique chance to get in a cross continent ride you may never do again.
In which case you blitz to Chicago and try and get past it on the first day - you can ride after rush hour after dark to just outside N Chicago if you are up for that.
Then across S Dakota at speed ( very pretty in the spring ) to Chief Joseph, Beartooth Pass ( if it's open ) and Yellowstone.
US fuel and accommodation is cheap.
Pick up the parks in Utah, Zion, Bryce Arches - Grand Canyon if you want even Death Valley and Yosemite, then across to the PCH at SAN Luis Obispo and go north until there is too much daily fog.
Catch Mount St. Helens and Mount Rainer then blitz to Vancouver.
Bottom line....either make it a proper tour and take 2 weeks and 3 weekends or fly it. This all depends on your being used to long touring days ( tho you can do short days once you cross the plains ).
If you are not used to mulit-day touring....gonna be a bit of a grind but many have done it on your type of bike.

My big worry is you are too early in the year to be in the mountains.
