Photo by Jim Koenigsaecker A 1969 Greeves Griffon 380 desert sled Jim Koenigsaecker just found in Northern California. The bike sat neglected for decades but is original and complete. Jim hopes to get the bike cleaned up and running soon. During the 1950s and 1960s English-made Greeves dominated the European motocross circuit and the desert races in the Southwestern United States.
