Off-road vehicle

An off-road vehicle, comprising:

• a frame;
• a plurality of wheels, the plurality of wheels comprising at least one front wheel and at least one rear wheel;
• a suspension assembly comprising a front suspension and a rear suspension, the front wheel being connected to the frame by the front suspension, and the rear wheel being connected to the frame by the rear suspension;
• a prime mover assembly comprising an engine and a transmission, the engine being arranged on the frame and comprising an engine body and a cylinder head connected to the engine body, the engine body defining a cylinder axis which slants upwardly and rearwardly, the cylinder head having a cylinder head mid-point where the cylinder axis intersects an exterior surface of the cylinder head;
• an exhaust assembly connected to the cylinder head for exhausting exhaust gas expelled by the engine, the exhaust assembly including an exhaust pipe, a muffler and a tailpipe, with the exhaust pipe running between the cylinder head and the muffler and with the tailpipe expelling exhaust gas from the muffler;
• a drive train mounted on the frame, the drive train comprising:
• a front drive train connected to the front wheel, the front drive train comprising a front drive shaft and a front differential having a front differential output axis;
• and
• a rear drive train connected to the rear wheel, the rear drive train comprising a rear drive shaft and a rear differential having a rear differential output axis;
• wherein a longitudinal mid-plane is defined as a plane perpendicular to a width direction of the vehicle where a center line of the vehicle in a width direction is located;
• wherein a cylinder front line running within the longitudinal mid-plane between the front differential output axis and a projection of the cylinder head mid-point on the longitudinal mid-plane has a cylinder front line length (L1), wherein a cylinder rear line running within the longitudinal mid-plane between the rear differential output axis and the projection of the cylinder head mid-point on the longitudinal mid-plane has a cylinder rear line length (L2), and wherein a ratio (L1/L2) of the cylinder front line length (L1) to cylinder rear line length (L2) is in the range from 0.4 to 1.8;
• wherein the transmission comprises a continuously variable transmission (“CVT”) having a CVT cooling air inlet on a front end of the CVT and a CVT cooling air outlet on a rear end of the CVT, with the CVT including its CVT cooling air inlet and its CVT cooling air outlet being on a first side of the longitudinal mid-plane;
• and
• wherein the exhaust pipe is arranged on a second side of the longitudinal mid-plane opposing the first side.
