What is claimed is: 1. An off-road vehicle comprising: a frame, a plurality of wheels arranged to support the frame, an internal combustion engine powering at least one of the wheels, at least first and second seats supported by the frame and disposed on opposite sides of the engine, and an air intake system including an enclosed conduit arranged to supply air from an inlet port to the engine, wherein the conduit includes a middle portion arranged below a floorboard of the vehicle, and at least a first portion of the conduit is disposed between the seats. 2. The off-road vehicle as set forth in claim 1, wherein the first portion of the conduit is disposed higher than a seating surface of the first seat. 3. The off-road vehicle as set forth in claim 1, wherein a second portion of the conduit is disposed between the first and second seats and above a seating surface of the first seat. 4. The off-road vehicle as set forth in claim 3, further comprising an air cleaner, wherein at least a portion of the air cleaner is positioned below the hood. 5. The off-road vehicle as set forth in claim 1, wherein the first seat overlaps the first portion of the conduit when viewed from a side elevational point of view. 6. The off-road vehicle as set forth in claim 1, wherein the engine comprises a cylinder block, at least a second portion of the conduit being disposed higher than the cylinder block. 7. The off-road vehicle as set forth in claim 1, wherein the engine comprises a cylinder block, and wherein the first portion of the conduit is disposed higher than the cylinder block. 8. The off-road vehicle as set forth in claim 1, additionally comprising a transmission and a shift lever configured to allow an operator of the vehicle to shift the transmission at least between forward and reverse modes, wherein the engine includes a cylinder block and wherein the first portion of the conduit is disposed between the shift lever and the cylinder block. 9. The off-road vehicle as set forth in claim 1, additionally comprising a transmission configured to transmit the rotation of the crankshaft to at least one of the wheels, the transmission comprising a v-belt arrangement and a v-belt transmission housing disposed to a lateral side of the crankcase, and at least an outlet air duct configured to guide cooling air out of the v-belt transmission housing, at least a portion of the air intake system overlapping with the outlet air duct when viewed from a side elevational point of view. 10. The off-road vehicle as set forth in claim 1, additionally comprising a transmission, a shift lever configured to allow an operator of the vehicle shift the transmission at least between forward and reverse modes, and a shift lever cover, at least a portion of the air intake system overlapping with the shift lever cover when viewed from a side elevational point of view. 11. The off-road vehicle as set forth in claim 1, wherein a downstream portion of the conduit extends from the middle portion vertically upwards to the first portion of the conduit. 12. The off-road vehicle as set forth in claim 1, wherein the middle portion of the conduit is arranged in a tunnel defined by a projecting portion of the floorboard. 13. The off-road vehicle as set forth in claim 1, further comprising an air cleaner, wherein the air cleaner is positioned higher than top ends of the plurality of wheels. 14. An off-road vehicle comprising: a frame; at least four wheels supporting the frame; an internal combustion engine having a crankcase housing a crankshaft configured to rotate and a cylinder block connected to the crankcase, the cylinder block being disposed toward a rearward end of the engine; at least a first seat supported by the frame and disposed on a left side of the internal combustion engine; at least a second seat supported by the frame and disposed on a right side of the engine; a transmission configured to transmit the rotation of the crankshaft to at least one of the wheels, the transmission comprising a v-belt arrangement and a v-belt transmission housing, the transmission also including a change speed transmission mechanism configured to shift the transmission between at least a parking state, a neutral state, a forward state, and a reverse state; an air intake system configured to guide air into the engine for combustion therein, the air intake system comprising a throttle body disposed between the first and second seats; and an exhaust system configured to guide exhaust gases away from the engine; wherein the throttle body is disposed between the shift lever and the cylinder block and above the crankcase. 15. The off-road vehicle as set forth in claim 14, wherein the air intake system comprises a plenum chamber connected to the throttle body and disposed between the first and second seats. 16. The off-road vehicle as set forth in claim 15, wherein the air intake system includes an inlet open to the atmosphere, the inlet being positioned higher than a seating surface of he first seat. 17. The off-road vehicle as set forth in claim 16, wherein the first seat is disposed in a position to allow an operator to sit in the first seat and operate the vehicle. 18.
