Abstract: An all-terrain vehicle (ATV) has a frame having front and rear ends, an internal combustion engine connected to the frame, the engine including a front portion and a rear portion, a single cylinder defining a cylinder axis, an air intake port defined in the front portion facing towards the front end of the frame, and an exhaust port defined in the rear portion facing towards the rear end of the frame. The ATV further has an exhaust assembly fluidly connected to the exhaust port. The exhaust assembly extends from the engine towards the rear end of the frame. The ATV further has a continuously variable transmission operatively connected to the engine, which includes a primary pulley being operatively connected to the engine, a secondary pulley, a drive belt looped around the primary and secondary pulleys, and a housing enclosing the primary pulley, the secondary pulley, and the drive belt.
