Indonesian biker rides into Moscow on 100-country tour
The 45-year-old said he was coping well with the chill of the Russian autumn and looked forward to the next stages of his trip, which will take him through neighbouring ex-Communist countries Ukraine, Moldova and Romania.
Polnaja left Jakarta on his BMW motorbike in April last year on a journey that he expects will total 330,000 kilometres and that he has dubbed a "Ride for Peace."
At a news conference accompanied by heavy rock music he attempted to explain his biker's philosophy, saying: "With a motorcycle there's no barrier.... I'm exploring this planet to feel what it feels, so I use my motorcycle to feel it.
"If I climb a high mountain I can feel the cold of the mountain, if I pass a forest I can smell the pine trees. If I cross a beach I can feel the heat of
the sun and the smell of the salt."
