Around 5,000 bikers from Europe and beyond gathered in Sevastopol for the annual festival Saturday on Ukraine's Crimea peninsula.
Putin, in Ukraine for talks with the country's new Russia-friendly leadership, had his black shirt sleeves rolled up as he motored toward a stage along a dusty road on the three-wheeled bike.
In sunglasses, black jeans and black fingerless gloves, the Russian prime minister clearly reveled in the moment, smiling and waving to the enthusiastic crowd.
From a podium, he described the motorbike as "the most democratic form of transport" and praised the bikers' free spirit.
He also urged them to unite in promoting safe driving.
