[1] Stationed in Germany with the military in the late 1960s, Coleman in fall of 1968 founded a motorcycle club with fellow US soldiers, named "Bones MC",[2] after a MAD magazine cartoon with a cigarette in a skeleton hand.
The club, originally based at Frankfurt, predates the first German charter of the Hells Angels, founded 1973 in Hamburg, by several years.
After Andrews retired from racing in late 1977, Coleman teamed up with Mark Bevans to contest and win the AMA Championship in 1979.
The team built a new chassis for 1980, powered by a Yamaha TZ750, and won the sidecar support race at the 1981 Formula1 Long Beach Grand Prix, which put the team on the cover of Cycle News, as well as earning them articles in Cycle World Magazine, American Motorcyclist and other publications.
He holds since 2011 an Bonneville Motorcycle Speed Trials AMA national record with a 1350cc Suzuki sidecar at 158.2 mph.
