The serrow especially the 250 is a great bike. Also consider the TTR 250, Louise used one for her trip, althought the seat is high you can fit a lowering link and drop the forks in the clamps a wee bit.
I have a TTR 250 and used it for a trip to Africa it performed flawlessley on the trip through spain sitting happy at 60-70 mph all day long.
If you are heading into the soft stuff the lack of weight is always a bonus, just dont load it up too much.
One important factor to consider is how much sand you will be riding in.
If you are crossing a lot of dunes, you may find that they sap the power of a smaller engine meaning its harder to keep momentum.
The Xt 600 is a great all rounder and there is a lowering link available, As above the DRZ 400 is lighter and nearly the same power (lots more than 250's) The DRZ can also be fitted with a lowering link.
If you are riding in a pack then electric start is the way foward with a set of jumper leads between you.
another option is the New Tenere plenty of grunt and good weather protection, but physically tall although again a lowering link is available. I've just got one and its great in the rough for a big bike thats also good on the road.
