A straddle-type vehicle comprises a front wheel and a rear wheel, an engine disposed between the front wheel and the rear wheel, an air cleaner box disposed above the engine, and a vehicle body behavior sensor provided on a periphery of the air cleaner box and located above a bottom wall surface of the air cleaner box.

Straddle-type vehicle

A vehicle includes at least: an engine; a transmission arranged on a rear side in a vehicle traveling direction relative to the engine; an exhaust pipe connected to the engine and discharging exhaust gas; and an exhaust muffler connected to a downstream end part of the exhaust pipe. The exhaust muffler is elastically supported on the transmission by an exhaust muffler support member arranged and located between the transmission and the exhaust muffler.

Utility vehicle

An exhaust muffler for a vehicle includes a muffler body coupled to an exhaust pipe and a tailpipe coupled to the muffler body. The muffler body has a plurality of expansion chambers, an exit communication pipe that discharges exhaust to the tailpipe from one of the plurality of expansion chambers positioned in a most downstream part of an exhaust flow path, and a spark arrester arranged in the exit communication pipe. An exhaust flow path narrowing portion is provided at an entrance portion of the exit communication pipe.

Exhaust muffler for vehicle

An exhaust muffler for a vehicle includes a muffler body that is connected to an exhaust pipe and that includes therein a plurality of expansion chambers. The muffler body has an upstream side cover that has an exhaust entrance connected to the exhaust pipe and that closes an upstream side opening of the muffler body, and a communication pipe that couples one of the plurality of expansion chambers positioned in a most upstream side part of an exhaust flow path and the exhaust entrance to each other. The exhaust pipe and the communication pipe are integrally joined to a peripheral portion of the exhaust entrance by a common welding bead.

An exhaust muffler for a vehicle includes: a sleeve portion made up of an outer sleeve and an inner sleeve; an upstream side cover that has an exhaust entrance and that closes an upstream side opening of the sleeve portion; and a downstream side cover that has an exhaust exit and that closes a downstream side opening of the sleeve portion. At least one of the upstream side cover and the downstream side cover has a peripheral flange portion that externally holds the sleeve portion. The peripheral flange portion has an outer sleeve holding portion and an inner sleeve holding portion. One end portion of the inner sleeve abuts on the inner sleeve holding portion so as to be slidable in a length direction of the inner sleeve. One end portion of the outer sleeve is fixed to the outer sleeve holding portion.

An exhaust system of a vehicle used for a parallel multiple cylinder engine in which a plurality of cylinders are aligned in vehicle width directions, at least comprising: an exhaust manifold that is connected to a plurality of exhaust ports formed in a front face of a cylinder head of the engine with respect to a vehicle traveling direction and that extends approximately horizontally in vehicle width directions along a front face of the cylinder head; and an exhaust pipe connected to an exhaust downstream end of the exhaust manifold.

A reserve tank layout structure of a motorcycle can secure a capacity of a reserve tank, and allow for easy checking of a remaining amount of a cooling water in the tank from the exterior. The layout structure is provided with a vehicle body frame, an engine supported by the vehicle body frame, a swing arm attached to the vehicle body frame so as to freely oscillate, a rear wheel supported by the swing arm, a wrapping transmission mechanism having an endless rope-like body wound between an output shaft of the engine and an axle of the rear wheel and transmitting power from the output shaft to the axle, and a reserve tank for storing cooling water of the engine, the reserve tank being disposed so that at least a part thereof is positioned at an inner peripheral side of the rope-like body.
