In a vehicle body frame structure for a saddle riding vehicle, including an engine, a vehicle body frame that supports the engine, and a swing arm that supports a rear wheel. The vehicle body frame includes a head pipe, a main frame that extends from the head pipe toward a rear of the vehicle along a path superior to the engine, a down frame that extends from the head pipe downwardly along a path anterior to the engine, a lower frame that extends from a lower portion of the down frame toward the rear of the vehicle along a path inferior to the engine, and a pivot support member that extends from a rear portion of the lower frame upwardly up to a position of a pivot shaft that rotatably supports the swing arm. The pivot support member includes a pivot support portion that supports the pivot shaft.

A suspension system for two-wheeler vehicle is disclosed. The system includes a rocker arm configured to transmit motion from a wheel to a spring element of a shock absorber using a rocker arm link, a length adjustable unit configured to adjust the length of the rocker arm based on a position of the rocker arm link upon moving a swing arm in up and down direction; to regulate the springing operation of the rear wheel based on the length adjustment of the rocker arm, a shock absorber configured to absorb vibrations.

A shock absorber includes a first damping force generating portion, and a second damping force generating portion. The second damping force generating portion includes a first flow path, an opening and closing member, an adjustment unit which adjusts a position of the opening and closing member in the axial direction, a second flow path which is located at a different position from the first flow path and passes through the piston in the axial direction, and a second valve which is disposed at an end portion of the second flow path at a side of a second end portion which is an end portion at an opposite side to the first end portion in the axial direction, and which opens and closes the second flow path.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame.

Transportation vehicles, suspension systems and related methods are provided herein. For example, a three wheeled vehicle is provided that can include a frame having a first side and second side and a front end and a rear end and a steerable front wheel secured to the front end of the frame. The vehicle can also include a first trailing wheel arm having a first rear wheel secure thereto and a second trailing wheel arm having a second rear wheel secure thereto. The vehicle can also include a central suspension joint secured to the frame on which the first trailing wheel arm is rotatably secured and the second trailing wheel arm is rotatably secured on either side of the frame. Further, the vehicle can include a horizontal linkage having a first end and a second end and a midsection between the first and second ends. The horizontal linkage can be pivotably connected to a pintle on the frame at the midsection beneath the first and second trailing wheel arms with the horizontal linkage linked to an underside of the first trailing wheel arm between the first wheel and the central suspension joint proximal to the first end of the horizontal linkage and linked to an underside of the second trailing wheel arm between the second wheel and the central suspension joint proximal to the second end of the horizontal linkage.

An electric motorcycle in which a driving force is transmitted to a wheel by connection with less waste. The electric motorcycle is one in which a battery is disposed in a position behind a handle and in front of a seat. A driving motor is located below the seat, and a lower part of a swing arm is supported by an attachment section provided in a pivot plate, a drive shaft that transmits a driving force output from the driving motor to a wheel being supported by the swing arm.
