Well you could take the Trans Siberian Highway to Never / Skovorodino, which is all asphalted.
Then you take M56 north from Never to Nizhny Bestyakh / Yakutsk, which is now about half asphalt / half maintained gravel road.
Then you take the M56 onwards and eastwards from Yakutsk to Magadan via Ust Nera. ... which is a maintained gravel road.
If you read the assorted ride reports to Magadan from RTWDoug and from Oisin, you will note thats the route they took (and which was more sensible on their larger, heavier bikes.) Search for them for more detail.
