A motorcycle (20) includes an electric motor (58) having an output shaft (70) defining a motor axis, a rear wheel (24) drivably coupled to the electric motor to propel the motorcycle, a swingarm (44) rotatably supporting the rear wheel, and a frame. The frame includes a main frame member (28) supporting the electric motor and the swingarm. A case (84) of the electric motor is a stressed member of the frame between the main frame member and the swingarm.
