Abstract: An upper arm projected line L5 is defined as a straight line formed by projecting an upper arm line L3 onto the projection line P1. a lower arm projected line L6 is defined as a straight line formed by projecting the lower arm line L4 onto the projection line P1. An intersection point Px1 between the upper arm projected line L5 and the lower arm projected line L6 is located in a region A1 defined higher than the horizontal plane P2 and defined farther outward in the right-left direction than the ski 4. The suspension enables turning performance of the straddle-type vehicle to be improved.

Abstract: A vehicle includes a front differential, a pair of constant-velocity joints, and a steering mechanism. The steering mechanism includes a pitman arm, a pair of tie rods, a pair of first link arms each connecting the pitman arm with a corresponding one of the pair of tie rods, and a pair of second link arms each connecting a corresponding one of the pair of first link arms with a body frame. In a plan view, at least a portion of each constant-velocity joint is located between first and second straight lines extending in a fore-aft direction and through first and second connectors extending between the tie rods and the first link arms. The first connector, the second connector, and at least a portion of each constant-velocity joint are located between third and fourth straight lines extending between the first and second link arms.

Abstract: A vehicle includes a first suspension between a body and a front wheel, and a second suspension between the body and a rear wheel. An angle θ1 represents a ramp brake-over angle, and angles θ2, θ3, and θ4 respectively represent angles corresponding to the ramp brake-over angle when the first and the second suspension are fully stretched, fully compressed and fully stretched respectively, and fully stretched and fully compressed respectively. When a wheelbase is not smaller than about 1340 mm, the angle θ1 is not smaller than about 55 degrees, a value θ2/θ1 is not smaller than about 1.25, a value θ3/θ1 is not smaller than about 0.9, and a value θ4/θ1 is not smaller than about 0.8. When the wheelbase is not smaller than about 1340 mm and not greater than about 2000 mm, a wheel travel on the rear wheel side is not smaller than about 360 mm, a ratio of a stretch-side value to a compression-side value (stretch-side/compression-side) of the wheel travel on the rear wheel side is not smaller than about 0.5, and a value θ2/θ1 is not smaller than about 1.25.
