I should say this is a clever move by Mr. Putin, be it in terms of "personal" ratings, or public diplomacy. After all, just a while ago Ukraine was one of the more "hostile" neighbor states.
Most notable lines, to highlight, are: "the bike is a symbol of freedom," and more importantly:
"Long live Russia.Well done, Vladimir Vladimirovich.
"Long live Ukraine.
"Хай живе байк [Long live the bike]."
UPDATE [July 25, 2010]: Apparently, Russia's representative to NATO, renowned Mr. Rogozin, made an appearance at the bike fest, too. See his comments [in Russian] here.
