This in-line 6-cylinder engine was the first Wright-manufactured motor to cool the entire cylinder and head. Weighing about 300 lb., it had 406 cubic-inch displacement and produced about 50 hp. in the 1911-version. It retained the characteristic compression release and foot pedal adjusted timing for the high-tension magneto from previous Wright engine designs.

The Wrights improved the motor in 1912 with cam-operated intake valves that produced 60 hp and earned the motor the nickname "6-60." Options included a muffler and dual ignition.

In 1913, the motor was equipped with dual Zenith carburetors, marking the first time a Wright motor had a throttle. Further improvements gradually increased the horsepower to 70, and finally 80 hp. The 6-70 had rubber shock absorbers to transmit power smoothly to the chain sprocket.
