Stop Your Motor is the Association's seventh studio album and their final project for Warner Bros. It marked the debut of keyboardist Richard Thompson, replacing original member Russ Giguere. The song "That's Racin'" was originally slated to be part of a proposed documentary about auto racing, Once Upon a Wheel, to be hosted by Paul Newman but the project fell through.
The album contained no charting singles and peaked at #158 on Billboard.
