If you're looking for great roads and magnificent views, you could do much worse than Norway. Western and Northern Norway are among the most wonderful places in the world with winding paved roads and great scenery. Getting there is the problem. Even South-Eastern Norway (where I live) is kind of boring, unless you know the small roads. (Feel free to ask!)
The best would be to ship your bike to Stavanger or Bergen and fly in. It may cost a bit, but if you compare it with the cost of driving there yourself, including accommodation and food? Probably not the worst deal, at least for one direction.
Western Norway should be ridden across the direction of the fjords. You get a nice variation of crossing mountains and driving around fjords, or getting a coffee break on a ferry. Distances are fairly short, so a trip should be easy to plan. Avoid planning more than around 300 km per day, and make sure you have time to take the scenic route. Maybe 5-6 days in Western Norway is plenty, and allows for some backtracking to get to all the best places.
Then head north. The E6 is boring, but luckily you can ride along the coast, following county road 17. I have not yet had time, but it is known to be amazing. In the main season there are a lot of RVs on the road. Make sure you have plenty of time, maybe 4 or 5 days? If you plan to sleep in hotels, booking ahead is required in the tourist season. This is a good time to stop at a boathouse for a couple of days and do some fishing or coastal exploring.

When you get to Bodø, you can take the Ferry to Moskenes at the end of Lofoten. Take a couple of days exploring Lofoten, but keep in mind that it is a pretty small place! I would make sure to also explore the other islands near Lofoten.
Vesterålen is great, and I would recommend spending a night in Nyksund, which is an old fishing village that has been turned into a kind of bohemian place with hotels and a pretty good restaurant. And the view! You can do whale safari from Stø. Driving along the outside of Andøya is amazing!
From Andenes at the north end of Andøya you can take a ferry to Senja, which is a secret gem along the coast. It's like what would happen if after Norway was almost done, half of the nature was still left and had to be crammed into a small island.
If you end up going, give me a ping. I sometimes go to fish and unwind at the place where my father grew up, 50 km east of Lofoten.
Spend a week in the archipelagos. That should give you plenty of time to experience everything.
After that, there's no big point in going further north, as the distances are too great for the views to justify. Going back through Sweden or Finland is possible, but roads are mostly pretty boring. An alternative is to take a coastal cruise on Hurtigruten back to Bergen. It's not cheap, but will offer some different views, and would be a proper place to relax celebrate!
But, the most important thing: Time of year. You do want to experience the midnight sun, and to get that you need to travel in June or July. Norwegian summer holiday starts the last week of June, and from early July onwards the RVs start to fill up the roads and accommodation gets harder to find. The best time to travel is in June. Most (probably not all) mountain passes in Western Norway should be open by then. For the trip I've outlined above, I would recommend to start around June 10, which would allow you to finish by the time it gets too crowded. Most, if not all, mountain passes in Western Norway should be open by then. This year I drove north on July 1st, and the traffic was light. One week later the ferries were full, and people were queueing for hours.
