A straddled vehicle comprising: a body frame; a seat including a seating surface to be in contact with buttocks of a rider; a rear wheel (Rw) including a tire to be in contact with a road surface (Rs) and a wheel surrounded by the tire; a swing unit including an engine, a transmission mechanism at least partially arranged to the left of the rear wheel (Rw) and arranged to transmit rotation of the engine toward the rear wheel (Rw), and an axle which is a cantilever shaft protruding to the right from the transmission mechanism, extends in a vehicle width direction along a rotation center of the rear wheel (Rw) and rotates together with the rear wheel (Rw) upon receiving the rotation of the engine transmitted by the transmission mechanism, the swing unit vertically swingable with respect to the body frame; a rear suspension at least partially arranged on the right side of the rear wheel (Rw) and attached to the body frame and the swing unit; and an exhaust system including an exhaust pipe arranged to guide exhaust gas emitted from the engine, a silencer at least partially arranged on the right side of the rear wheel (Rw) and arranged to emit the exhaust gas guided by the exhaust pipe from an exhaust port opened to the atmosphere, and a bracket (91u, 91L) fixed to the exhaust pipe and the silencer, wherein the engine includes a piston arranged to reciprocate in accordance with combustion of fuel, a crank shaft arranged to rotate in accordance with reciprocation of the piston, and a crank case housing the crank shaft, the swing unit further includes a support arm including a silencer attached portion (92u, 92L) to which the bracket (91u, 91L) of the exhaust system is attached, and a suspension attached portion to which the rear suspension is attached not via the exhaust system, the support arm being at least partially arranged on the right side of the rear wheel (Rw), the support arm being integral with the crank case or fixed to the crank case, a rear end of the support arm is arranged on the right side of the rear wheel (Rw) and arranged at a position inside of an outer circumference (To) of the tire and further to the front than the rotation center of the rear wheel (Rw) in a side view, the suspension attached portion does not overlap the silencer attached portion (92u, 92L) in a side view, characterised in that at least a portion of the suspension attached portion is arranged further inward than an outer end of the silencer attached portion (92u, 92L) in the vehicle width direction in a plan view, and an extended line (Le) of a center line (Ls) of the rear suspension intersects with the seating surface of the seat in a side view. a body frame;
