Hi Leon, I haven't done it for years and it seems to have fallen out of fashion, but I would not enjoy tackling MH3 on GS310s. The old Tornados would have been a better bet (other Marrakech renters still offer them).

As Warden says, up over the Atlas watershed to Agoudal (piste - part of MH1) and back down (road) would be much more memorable, and for the right reasons. Or dodge Todra and carry on east from Ait Hani towards Amellago. Nice lodgings there and a great canyon ride down to Goulmina (MH13).

As also mentioned, the Telouet diversion is also well worth it, and so is MH4, sealed or otherwise. MA12 is great on any bike too, and is now sealed (or dead easy) from near Assaragh to Agadir Melloul.

Safety issues in Morocco are the same as riding remote areas in any foreign country, so ride appropriately and stick together. In towns, if wandering away from the bikes, don't leave anything on them you can't afford to lose. Same as anywhere. Morocco south of the Atlas is much more chilled than the north.

Lodgings will invariably help with parking your bikes off the road, even inside the lobby if possible. But bike theft is much less of an issue than south of France, say.
Like the book suggests, on a moto keep it simple and use cheap lodgings instead of carting camping clobber – that's more of a car thing. End of November it's dark by 6ish. Nicer to be tucking into a steaming tajine in a cosy Berber auberge with fast wifi than stuffed in a chilly tent over a Primus while your airbed slowly deflates.

Or, if by 'safety issues' you mean being attacked / robbed because you're a foreigner in a Muslim country, you'll be very pleasantly surprised ;-)
Morocco is more like Spain than Libya.
