The vehicle includes a longitudinal axis extending from the forward end to the rearward end. A single or tandem seating arrangement is arranged along the longitudinal axis in certain embodiments. The engine is secured to the frame. The engine includes at least one cylinder and a crankshaft with a crankcase fastened generally beneath the cylinder. A transmission is coupled to the engine crankshaft. The transmission extends forwardly from the crankshaft toward the forward end of the frame along the longitudinal axis. A side-by-side seating arrangement is secured to the frame generally along an axis substantially perpendicular to the longitudinal axis of the vehicle. An air intake is provided at the forward side of the cylinder with an exhaust out the rearward side.
