Stop Your Motor is the sixth studio album by American pop band the Association, and their final album released on Warner Bros. Records. It marked the debut of keyboardist Richard Thompson, replacing original member Russ Giguere. The songs "That's Racin'" (original titled "I'm Going To Be A Racin' Star") and "The First Sound" were initially slated to be part of a proposed soundtrack for a documentary film about auto racing, Once Upon a Wheel, hosted by Paul Newman but the soundtrack failed to materialise beyond a promotional level (sponsored by Coca-Cola). The title song from the documentary, as composed by Terry Kirkman, never saw an official release.
The album contained four singles; however none of them charted and the album peaked at number 158 on Billboard.
