Last year I posted a possible extension of the IHS route, following a loop around the Frank Church Wilderness.
Now that the snow will roughly have melted away and wild fires are not yet spoiling the awesome views, it may get more interest.
The total distance is 553 mi and the elevation gain 53700 ft.
A map and altitude profile that can be zoomed-in can be found on

I never rode the Loop in its entirety. Mid-June 2014 I rode from Stanley to Shoup, but the Horse Creek Pass was still blocked by snow, as was the Magruder Rd. In late August 2015 I rode from Alta Montana to Warm Lake, except for the section between Riggins and Burgdorf that was blocked by wild fires (detour from Riggins over New Meadows and McCall to Burgdorf).
If you want a paper map covering half of the Loop, look for the Butler Motorcycle Maps - Idaho Backcountry Discovery Route. It runs in the opposite direction and covers most of the route between Warm Lake and Alta Montana in detailed maps at a scale 1 inch = 5 mi. It has some additional Points of Interest, but does not have the detailed list of services as the above.
