Ancient Iron Motorcycle Club (AIMC) was founded in 1981. AIMC held the First West Coast Bike Blessing ever on April 11, 1982. The club has continued as a tightly knit brotherhood of serious American-made motorcycle riders since its formation. Club membership is by invitation only; the membership process can be long and requires complete dedication and commitment. AIMC is based in Santa Clara County, California, and proudly displays a California bottom rocker. The patch itself was inspired by a tattoo on one of the founding members.
