The Indian Motorcycle Company of America (IMCA) manufactured Indian Chief motorcycles in Gilroy, California, from 1999 to 2003.
These initially used clones of Harley-Davidson Evolution engines built from S&S parts.
Later versions used the in-house "Powerplus" engine.

A new company began production of Indian Chiefs in 2006 in King's Mountain, North Carolina.
These were updated versions of the IMCA Chief.
Production of the Chief was moved to Spirit Lake, Iowa, after Polaris Industries bought the company.
