  • Patent number: 8646788
    Abstract: A saddle riding type vehicle includes a vehicle body frame 4 constituting the vehicle, a front wheel disposed steerably on the vehicle body frame 4, a steering shaft 27 transmitting a steering input from a rider to the front wheel, and a steering damper 36 giving a steering mechanism 57 an attenuation force relative to rotation of the steering shaft 27. The steering damper 36 includes a damper case 72, a vane rotatable in the damper case 72, and an arm 73 directly connected to the vane and extending to an outside of the damper case 72. The damper case 72 is disposed between an upper steering shaft 27a and a lower steering shaft 27b to form part of the steering shaft 27, and the arm 73 is directly connected to the vehicle body frame 4.

  • Patent number: 6840338
    Abstract: A half-track all-terrain vehicle having an independent suspension system that provides an improved vehicle ride and facilitates traversing obstacles. The vehicle includes a frame, a pair of beams that each holds front and rear wheels, and a suspension system extending between the each beam and the frame. The suspension system includes a plurality of cushions. The cushions are tuned such that forward cushions have a relatively greater suspension stroke than the rearward cushions and thereby permit the front wheels to engage the ground sequentially before the rear wheels when the vehicle goes over a step or drop off. The suspension system is further tuned to permit the vehicle to traverse an obstacle having a height that is slightly lower than the frame clearance by permitting the front wheels to lift vertically to a distance essentially equal to the frame clearance.
