Helge Pedersen may be one of the only motorcyclists on this list to have used a modern-day adventure bike, or really, one of the first adventure bikes: the BMW R80 G/S. Pedersen would span the globe, crossing through 77 countries and accumulating 250,000 miles over 10 years. His travel across the Sahara desert and through the jungles of South America would be fraught with poisonous plants and animals, as well as lots of sand and mud. Helge Pedersen is still actively photo-journalizing the world, so perhaps he should play himself in next summer’s blockbuster moto-film, 10 Years on 2 Wheels.
