No particular order for the rest but I have to vote Hwy 1 as numero uno.
Hwy 1 <----------- Heaven on 2 wheels - my favorite section is up from the coast up to Leggett
Lolo Pass
Beartooth & Chief Joseph
Anywhere in UT
89 in AZ
AlCan from Watson Lake to Whitehorse
The scenery on the road to Stewart/Hyder
CA 58, 36, 33, 89, 96 and many more
BRP mid-week in the off season
101 Oregon Coast
Maine coast
Lots of cool roads in SE BC as well
I have to say one of my most favorites ever was the road between Watson Lake and Whitehorse at speed: 258 miles of perfect sweepers(and no Mounties):
