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.

Abstract: A vehicle has a frame, wheels, left and right seats each having a seat base, an internal combustion engine disposed rearward of the seat bases, an air induction system fluidly connected to the engine, at least one side body panel and an access panel. The air induction system has an air inlet, an air filter, and a throttle body. The at least one side body panel is connected to a side of the frame and defines an aperture. The access panel is movable between a first position and a second position. In the first position, the access panel is connected to the at least one side body panel and covers the aperture. In the second position, the access panel exposes the aperture. The air filter is accessible through the aperture when the access panel is in the second position. A method for removing an air filter is also disclosed.
