've been there in August 2010 by motorcycle, too, riding overland from my hometown in northern Italy to the Azeri border and back.

I can tell you that Georgian and Armenian people are really friendly and landscapes gorgeous.
Entering Georgia from Turkey (Sarp border station) has been really easy: after about 90 minutes to exit Turkey due to a veeeery long line of cars and coaches, it took only 10 minutes of formalities to enter Georgia, with Georgian policemen that let me and my girl pass to the front of the line to let us in very shortly (with many "Welcome to Georgia" and smiles for us): the easiest border crossing out of Europe ever, for me.
If you get into Turkey from Georgia at Posof-Vale border, pay attention on the Georgian side: road turns suddenly from asphalt to gravel and small rocks right some km. before the border beyond a hump (you don't see the beginning of the gravel part at all while you ride, and it would be easy to fall if you ride fast).
Traffic police are everywhere, friendly, helpful and they never bothered us.

English is not widely spoken, better if you could learn some words of Russian.

Pay attention to the roads: even the smoothest tarmac may hide deep potholes, so don't ride fast even though you think you could.
Main roads are OK or quite OK, but secondary roads are very often in bad conditions with gravel and scattered potholes.

Traffic either in Georgia and Armenia is often crazy, cars pass one another even if the curve is "blind", so don't expect that nobody is coming against you on your lane even though you would not dare to pass due to lack of visibility: between Gori and Tbilisi I've even seen a family on a Lada pass the Police with roof lights on and white continuous line!

You'll find good accomodation, don't worry (see also this thread of mine http://www.horizonsunlimited.com/hub...caucasus-54816).

While in Georgia, don't miss the Georgian Military Road that is simply stunning, and in Armenia... well, don't miss anything there!

If you need more info, feel free to ask.
