This is a great road for trailies or supermotos (I did it on a Buell XB12X) due to the road surface as you climb into the mountains and the very tight and twisty hairpins. As you leave Revest stay on the D950 till you get to Haut Labouret. Come off at Haut Labouret and take the D518 for Ferrassieres. When you get into Ferrassieres take a right hand turn heading for the col de Lhomme Mort (translates as the col of the dead man!!. Carry on the mountain pass till you get to a T junction and bear right onto the D542 and head for Sederon.
