A motorcycle suspension system comprising an axle block on each side of the motorcycle, each axle block for receiving one side of a rear wheel axle, and each axle block rotatably connected to a motorcycle frame member with a bearing. Each axle block may be rotatably connected to the rear wheel axle with a bearing.

A saddle-type vehicle includes an engine, a vehicle body frame, a fuel tank, and a fuel pump configured to supply fuel from the fuel tank to the engine. The vehicle body frame includes a head pipe, one main frame extending rearward and downward from the head pipe, a cross member connected to the rear end of the main frame and extending in the vehicle width direction, a pair of left and right body frames extending downward and rearward from the cross member, and a pair of left and right seat rails connected to the pair of left and right body frames, respectively. The cross member is disposed in front of the fuel pump. The pair of left and right body frames are arranged to sandwich the fuel pump in the vehicle width direction in a top view, and are connected to the cross member.

Embodiments of the present application disclose a coupling device and an all-terrain vehicle. The coupling device includes: a first coupling member including a first tube portion and a first solid portion coupled to the first tube portion; and a second coupling member including a second tube portion and a second solid portion coupled to the second tube portion. The second solid portion is detachably coupled to the first solid portion. In the coupling device of embodiments of the present application, the first coupling member includes the first tube portion, and the second coupling member includes the second tube portion, thereby greatly reducing the weight of the coupling device and transportation costs of the coupling device.

Systems, methods and apparatus are provided through which in some implementations a motorized tricycle includes a lean mechanism and an active system that is operably coupled to the lean mechanism that receives an signal indicative of an interaction with human, that is operable to detect a lean of the body of the human and that is operable to receive a sensed movement on the seat via multisensory devices, and to generate and send a signal to the lean mechanism from the signal, the lean and the sensed movement.
