If I may offer my opinion:
The selected route will take you mainly along the E6 road northbound.
While E6 is great if you are pulling a trailer, you want to avoid this road by all means if you ride MC.
I therefor humbly offer some alternatives:
Leaving Oslo: Proceed towards Elverum (it will start you out on E6, but that's ok, getting out of Oslo asap is a benefit).
Close to Elverum, turn northbound on road # 3, and head for Røros. My favourite place in Røros is
Bergstaden Hotel. (It's located smack in the middle of town, and your boss will love it (free parking as well).
Røros is an historic place that is well worth spending some time to sort out.
Hence, leaving Røros, I suggest you aim for Steinkjær.
Unless Trondheim is on your bucketlist, a more fun road is to proceed via Snåsa and then follow E6 from Stjørdal to Steinkjær. My favourit hotel there is the
Best Western Tingvold Park Hotel. When searching for it, the price may appear a bit 'heavy', but keep in mind, the price includes both dinner and breakfast.
Next day, I suggest you continue on E6 (which, north of Steinkjær is Ok) and aim for Mosjøen. This is a moderate distance, and if you love old bikes, 20 min. north of Mo i Rana there is a small Motorcycle museum:
Arctic Circle Motorcycle museum. It's a small building, and even if it is located next to the E6, it is easily missed (thus, if of interest, try to set it as a waypoint in the GPS). The museum will set you back an hour.
Reaching Mosjøen, my prefered hotel is
Fru Haugans Hotel. In their booking, they offer Parking if you pay extra, but there is a free public parking across the street, and with a MC, there will always be space available.
From Mosjøen you are getting closer to Lofoten. The suggested route will take you to Bognes, ferry to Lødingen. This is the main road, and a safe bet. HOWEVER, in my opinion, whats worth seeing of Lofoten is close to and west of Svolvær. Thus I suggest, rather than do the Bognes ferry, if you turn westbound 30 min prior to Bognes and aim for Skutvik, and do the ferry Skutvik-Svolvær instead, 2 hrs (and it's for free due to low passenger numbers), the ferry will take you to 5 mins from Svolvær. The catch is, the ferry does only a couple of runs each day, a morning run and an afternoon run (starting 19.55 from Skutvik) and this will bring you to Svolvær 22.00 in the evening. Normaly, this may appear to be late. But in Svolvær, this is no sweat. The Hurtigruten do their evening stop around 21.30, and stays for a while, and this means everything of interest (food and beverage) is accessable for a good while after you arrive.
There are two decent hotels in Svolvær, I have no preference (Scandic and Thon Hotel), but if you travel with more than 1 bike (i.e need several rooms), there is also the option of 'Rorbu', which is a cabin-type facility placed on a pier. (if ov interest, check out , located 3 min walk to the center of the city).
Updated timetable for ferry routs in the region:
Ferry timetables
I suggest you spend three nights in Svolvær and do daytrip, 1 day westbound and one day north-eastbound.
Then, rather than doing the long (and congested) ferry Moskenes-Bodø, (unless Bodø is a 'must see' place for you), I suggest you do the morning ferry from Svolvær to Skutvik.
That said: If the weather is good (as in 'not raining), rather than doing the E6 again southbound, a better choice would be to do the senic and coastal road #17 and aim for Mosjøen again. But starting from Svolvær will make this too long for one day ride.
Doing E6 to Mosjøen from Skutvik is 425 km, and the ferry, either you choose an earlybird from Moskenes-Bodø, or the shorter one Svolvær Skutvik, it will still be a looong day. If number of days are limited, consider cutting to two nights in Svolvær, doing one daytrip north-eastbound, and the next day, doing the westbound ride and aiming for the 15.00 hr ferry from Moskenes that will bring you to Bodø at 19.00 hr. and spend the night in Bodø.
This will give you a great start for doing the #17 senic route ending up in Mosjøen again, and from there on pick up your route aiming for Namsos and so on.
In the Lofoten area there are limited capacity of hotels, and booking ahead of time is highly recommended, even if august is passed the high-season. There are lots of coach companies that run tours with large busses, and a couple of bus-loads will easily fill up a hotel.
The ferry Moskenes-Bodø offers booking ahead of time. But keep in mind: They only book to 50% capacity, and the pre-booked ticket may cost up to 50% more. Thus, even if fully booked, there will still be space available, on a first served basis. We have done this several times, and lining showing up 45 - 60 mins prior to departure has never left us standing.
That's my 2c
