I have now spent my week on a beemer i Morocco, and have safely returned home to this land of ice and snow...
I want to thank everyone of you who have helped my plan my trip, and especially to to you Chris! Your book was a great read and it also gave me something to ponder while on the saddle.
I ended up opting for mostly the sealed roads, as I never really got comfortable on my GS800. I haven't ridden one previously, and when I went on gravel and narrow roads it didn't give me a stable feel, always felt top heavy with a tendency to tip over.
Anyways, the roads I did ride on.
From Marrakesh to Ouarzazate I was adviced to turn off after Taferiate and take the P2016 to Zerkten. Then the next part of the N9 to miss is the detour down the P1506 via Ait Ben Haddou.
I had a day from OZT via the Flint Oasis to Tazenakht, the to Agzd then south before returning to OZT. Knowing what I know now, I could have taken to Nkob to Tinghir. Start early doors, and Tinghir is quite achieveable.
Did a day to Dades and Toudrah gorges. Dades was pretty, Toudrah was awesome! Getting there ahead of the tourist buses was key.
I will definitely return to Morocco, and ten days will probably be the minimum stay next time round.
