A two-wheeled vehicle includes a frame having a front frame portion, a mid-frame portion, and a rear frame portion. The mid-frame portion is coupled to the rear frame portion and the front frame portion. The vehicle further includes a plurality of ground-engaging members for supporting the frame. The front frame portion is removably coupled to the mid-frame portion with a plurality of frame members extending between the front frame portion and the mid-frame portion.

The invention relates to a bicycle (100) having a frame structure (200) that comprises a swingarm structure (225) including a first substantially U-shaped sheet metal part for holding a wheel (103), the frame structure further comprising a frame bridge (219) consisting of a second substantially U-shaped sheet metal part. The first U-shaped sheet metal part is bent substantially in a first bending plane (P) to form a first U-shape, and the second U-shaped sheet metal part is bent in a second bending plane (Q) to form substantially a second U-shape. The first bending plane extends substantially perpendicular to the second bending plane.

A bicycle can include a forward frame triangle that can include a top tube, a bottom tube, a bottom bracket, a structural seat tube, a compliant seat tube, and a pair of seat stays. The top tube can have a first end connected to a head tube and a second end. The bottom tube can have a first end connected to the head tube. The bottom bracket can be connected to the bottom tube. The structural seat tube can be connected to the bottom bracket and the top tube. The compliant seat tube can extend in an upward direction from the bottom bracket to the top tube and within the structural seat tube. The compliant seat tube can be coupled to the forward frame triangle such that the compliant seat post can bend within the structural seat tube.

The radiator is disposed between the accommodation box and a front wheel. A rear edge lower portion, which is at least part of a rear edge, of the cover with which an opening of the accommodation box can be closed and opened is inclined obliquely in side view of the vehicle body, and the cover is supported in an opening-forward manner with reference to a support shaft disposed along the inclination.

A saddle riding vehicle includes: a body frame having a head pipe and a main tube extending from the head pipe; an engine disposed below the main tube; a down frame extending downward from the body frame and disposed in front of the engine; and a radiator disposed in front of the engine and on a side of the down frame, wherein an opening which opens rearward is formed in a fan shroud which covers a rear surface of the radiator, a radiator fan is disposed in the opening, and a front surface of the radiator fan is disposed such that an axis of the radiator fan is inclined toward an outside with respect to a direction in which a surface of a core of the radiator is directed so as to increase a gap with respect to the core from an outer side toward an inner side.

A two-wheeled vehicle includes a frame, a front ground-engaging member, a rear ground-engaging member, and a rear suspension assembly operably coupled to the rear ground-engaging member. The rear suspension assembly includes a first swing arm, a second swing arm, and a pivot axle extending between the first and second swing arms. And, rotation of the pivot axle is configured to adjust the position of a portion of the frame relative to the first and second swing arms.
