Hi Basmati:
Welcome to the forum!
There are so many interesting possibilities for a 9 day trip out of Tangiers. I honestly don't know where or how to begin to answer your question.
What you might want to do, to make your planning more effective (and more fun) is pick up a copy of the most recent Michelin National map for Morocco. This is Michelin Map 742. Be aware that a new version was released in 2018, don't accidentally buy an older version.
There are many ride reports here in the Morocco forum, and lots of articles that explain how the process of getting on and off the ferry, clearing customs, getting insurance, etc. works (it's a trouble-free process, no surprises).
You'll also find lots of information here about trip logistics - how to get money out of ATMs with your European or North American ATM card (easy to do), what not to bring with you (drones), unique Moroccan peculiarities (for example, online Google Maps won't work in Morocco), and stuff like that.
One of our forum members, Tim Cullis, maintains an excellent website called
Morocco Knowledgebase, it is well worth a visit.
The roads in Morocco are generally in very good condition, I did a one-month tour there last year on my ST 1100 (Honda PanEuropean) - for sure not an 'off-road' bike - and had no troubles at all.
