Abstract: An off-road vehicle includes a frame and four wheels that support the frame. Two seat assemblies are disposed side by side on the frame. The seat assemblies are separated from each other to define a space therebetween. An engine powers the wheels. The engine defines an air intake port that communicates with a combustion chamber. An air intake system delivers air to the intake port. At least a portion of the air intake system extends through the space.

Abstract: An off-road vehicle includes a frame and wheels. An engine of the vehicle has a crankshaft. A transmission transmits the rotation of the crankshaft to the wheels. A housing houses a transmission mechanism of the transmission. The housing has an air inlet duct through which ambient air enters the housing and an air outlet duct through which the air leaves the housing. The air inlet duct has an inlet opening. The outlet duct has an outlet opening. The inlet and outlet openings are positioned higher than the wheels.

Abstract: An off-road vehicle includes a frame and a plurality of wheels. An engine powers the wheels. An air intake system supplies air to the engine. The air intake system has an air inlet through which ambient air enters the intake system. The air inlet is positioned higher than the wheels. An air intake duct extends rearward to the engine from the air inlet. At least a portion of the air intake duct is positioned lower than the tops of the wheels.

Abstract: An off-road vehicle includes a frame and four wheels that support the frame. An engine powers the wheels. The engine is mounted on the frame. The frame includes multiple frame members that surround the engine. One of the frame members disposed behind the engine is detachably affixed to the rest of the frame members. The frame members are divided into first and second groups. The first and second groups are offset fore to aft relative to each other and overlap with each other in a rear section of the first group and in a front section of the second group. The rear section of the first group defines a bent portion coupled with the second group. The front section of the second group defines a bent portion coupled with the first group.

Abstract: An off-road vehicle has a frame and at least one wheel. A suspension arm suspends the wheel from the frame. The frame includes at least one horizontal member that extends generally horizontally fore to aft. A set of retainers are attached to the horizontal member. The retainers are spaced apart from each other fore to aft. The retainers swingably retain the suspension arm therebetween.
