I did this trip in August. Me and 2 others, on bigger bikes, the smallest was mine, a 600cc.
Its just over 700km and a liesurely ride took us 10 hrs one way.
The scenery is fabulous and the road fantastic.
We heard that fuel was an issue so took lots along with us in our 4x4 which follwed with drum full of it.
Plan B to deal with bad fuel was that we took along a good measure of muslin cloth (makhmal) to be used in many folds acting like a filter.
