What is the normal idling RPM?
For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm. Two-cylinder motorcycle engines are often set around 1000 rpm.
