Starting in Medford, head over toward Grant's Pass, and pick up Hwy 62 and go north, taking the route to the west side of Crater Lake. (I assume you've been there already)
If you stay straight ahead at the junction, 62 will go back to the southeast. Stay ahead on what is now 230, which winds around the north side of Crater Lake park and intersect with U.S. 97.
Go north on 97 to Redmond, then take Hwy 26 to the east. This will take you through Prineville and John Day. Past John Day you will come to Austin Jct. There you should turn off onto Hwy 7, which will take you to Baker City.
From Baker City, pick up 86, which will route you through Richland and Halfway, then into Hell's Canyon. At Hell's Canyon, turn right, riding on the west side of the Snake River, and at Brownlee Dam, you come over onto the Idaho side and Hwy 71 takes you the 30 miles out to Cambridge. It's a beautiful, twisty road, very scenic. At Cambridge, head north on U.S. 95 to New Meadows, where you turn north, still on 95, through Riggins, up Whitebird Grade, and Grangeville.
At Grangeville, pick up Idaho Rt. 13 which is a twisty road that takes you to Kooskia (pronounced Koosky) at the intersection of Hwy 12, billed as one of the best motorcycling roads in America. The ride along the Clearwater River and over Lolo Pass is amazing. At Lolo Pass you continue on, into Montana, where 12 connects to Hwy 93. Going north gets you into Missoula, and from there, I can't advise further, as I'm not that familiar with Montana, however if you continue north on 93, you can pick up 200 that winds back to St. Regis, where you'd have to hit I90, going back into Idaho, through Wallis, Kellog, and eventually Coeur D'Alene.
At CDA, head north to Sandpoint, then west on Hwy 2 to Newport, WA, then across northern Washington out to Hwy 97, where you can turn south and take 97 all the way back down into Oregon and home.
Just a suggestion, but it's a route that is altogether scenic, with interesting roads to ride.
