First of all, we wish you welcome to Norway!
Traveling in some of this areas may wary a lot from year to year depending of the weather. Even the main roads may sometimes be closed for far weeks if the weather becomes to bad. In the mountains the the snow may make walls of several meters high, and parking will just be impossible. The road authorities keeps you informed at internet:

Most toll roads are free for MC driving.
It is special requirements for winter tires in Norway, a limited number of steel dubs are allowed within some other limits. (I guess these are equal to Swedish rules)
