Not having experience with many other continents, I might be able to offer a couple of great roads in the United States, where riding varies greatly and you can find something to suit any level of adventure you want to pursue.

Utah - try the White Rim Trail, or Mokie Dugway...as well as perhaps the Potash Road. Colorado is filled with loads of mountain passes, off road trail riding, etc. to suit any skill level. Best wishes!

You taking a GSA1200 to Mongolia... AND looking for good routes ;: )

I watched Long Way Round, an that does not make me a specialist, But since I also ride a GS1200 and an XT660, I know which one I will take to Mongolia and which one not :)

I suspect, if I had a 250, that would have been my best option.

But the rest of the road... perhaps the 1200 is not to bad.

I hear you and am thinking more about my 650XC or perhaps the new Africa Twin!

Georgia (The country)
 

If you pass through Georgia take some time to explore and you'll be rewarded with some fantastic scenery and interesting roads.

From Batumi to Akhaltsikhe is a bit beat up with lots of roadworks in progress but the views from the top of the pass are nice. After Akhaltsikhe the road is good and nice and twisty all the way down to Vardzia as it follows the river along the valley. I took the road from Vardzia to Alkhalkalaki whch is similar to the road down to Vardzia and then the dirt road over the mountain pass to Bojormi, a terrible pot holed road to the top of the pass but the views are spectacular then the road improves down the northern side.

The road through Tbilisi National park is a good surfaced twisty road with little traffic the days I was there and again plenty of spectacular scenery.

If you fancy some more difficult road the one into Tusheti National park is not to be missed with lots of twists and turns high up into the pass at just under 3000m and then down into the park itself, again very spectacular scenery.

In southern Chile

I drove RTW , 11 month / 83.000km. One of the best routes is Chachapoyas - Celendin, Peru.

I can second that! Actually even further to Encañada. Its THE most insane road I have ridden on my + 200 000 kms RTW trip!

Just about anywhere in the Western Cape, South Africa. Especially from Gordons Bay round to Betty's Bay and beyond. Also Chapmans Peak Drive or up in the Cederberg Mountains or the R62. Actually just about anywhere in the Western Cape!

Now you're talking. Also don't forget the stretch from Caledon to Bredasdorp, lovely fast sweeps.

I currently live in Zhejiang province, Eastern China, which is considered to be Chinese bike heaven. Beautiful deserted mountain passes everywhere, if you are willing to take the slog out of the city.

Alps POI's (lesser known passes and roads)
 

I started an Open Street Map with .gpx points of many lesser know roads and passes in the greater european Alpine region. One layer is the suggestions from other folks at advrider.com , the other layer is over 200 gpx points from one riders decades of travels.

The layers can be toggled on/off. Additionally, the camping .gpx files found elsewhere on this site can be uploaded as a map layer. Very useful, I think.

Europe moto roads and POI's off the beaten path - uMap

I started a thread for additional contributions.

Southern Africa

Western and Eastern Cape and Lesotho boast many scenic roads and beautiful mountain passes. The most spectacular roads in southern Africa are IMHO the following:

Swartberg Pass, Western Cape (S33 18.996 E22 02.611) north to Prince Albert. Just north of the summit turn westwards for a detour to Gamka Kloof (De Hel). It's a 60 Km. Cul-de-sac with kiosk and campsites.

Follow the road from Maclear (Eastern Cape) via Naude's Nek Pass (S30 45.882 E28 06.330) to Rhodes - Carlislehoekspruit Pass (S30 43.126 E27 57.410) - Volunteers Hoek (Bidstone) Pass (S30 42.900 E27 49.840) - Lundean's Neck Pass (S30 38.827 E27 44.530) – Telle Bridge Border Post to Lesotho – Quacha's Nek Border Post back to South Africa – Underberg (KZN) – Sani Pass (S29 35.290 E29 17.564) – northwards along the “Roof of Africa” route – Oxbow - Monontsha Pass (S28 35.197 E28 41.386), Border Post - Phuthaditjhaba (South Africa).

And you shouldn't miss the Victoria Falls. Of course the Game Reserves in South Africa are well worth a visit, but m/c are not allowed. So you would need to do a day trip with local safari companies.

fantastic and following ( i too am planning )
 

Northern California - Sierra Foothills Famous HWY 49 ( you can camp at my property also ) amazing curvy and great historic lil gold rush towns also its the best ride.. from west of Lake Tahoe, down to Yosemite ( 3 hours due east of San Francisco Bay Area)
