Hi Louis:
Just to be sure... have you arranged for liability insurance for your moto?
Normally, policies that are issued in Canada are also valid in the USA, and vice-versa. But there have been a number of posts here in the forum recently where folks have reported difficulty getting liability insurance to cover a European motorcycle in North America.
In Canada, the penalties for operating a vehicle without liability insurance are very severe.
Also, I am not sure what route you are planning to take, but I recommend you proceed from Calgary airport to Banff (about 100 km), then ride the Icefields Parkway (Highway 93) from Banff up to Jasper, then continue on your way from there to Alaska. The Icefields Parkway is one of the world's great roads and is not to be missed. Fill up with fuel before leaving Banff, there is very little commercial development on Highway 93. In fact, gas stations are few and far between on the route up to Alaska, so it's generally not a good idea to pass by a gas station anywhere in rural Alberta if you have less than half a tank of fuel.
After you reach Jasper, you can take Highway 40 north to Grande Prairie and at Grande Prairie you can rejoin the conventional path to Alaska.
Do be sure to have an old-fashioned oval white "F" country sticker on the back of your moto. The new EC spec license plates with the blue country code in the corner are not known or recognized in Canada or the USA.
Lastly, be aware that to enter Canada by air, you need to fill out a whole bunch of data on the "ArriveCan" app, which you can access either by
website or by downloading the ArriveCan app for your smartphone. I recommend you download the app. You have to create an account, upload scans or photos of your COVID vaccinations, and jump through all sorts of other hoops, and this can only be done within 72 hours of the
arrival time of your flight in Canada. So investigate that ahead of time and get the account set up early.
