Abstract: To provide a vehicle body cover structure for a saddled vehicle, capable of achieving restrictive improvements on rigidity of the vehicle body cover. A vehicle body cover structure for a saddled vehicle includes a radiator shroud formed of a fiber-reinforced resin covering an outside of a vehicle body. The fiber-reinforced resin is formed of a cloth woven from warp threads and filling threads formed of fibers. In the vehicle body cover structure, the radiator shroud has the cloth disposed thereon. The cloth has disposed thereon a bisector that divides an angle formed between the warp threads and the filling threads into two equal parts. The bisector is disposed so as to extend along a line segment that connects between a third mounting portion to be fixed to a vehicle body side and a front end portion that is farthest from the third mounting portion.

Abstract: A vehicle body frame structure for a saddle riding type vehicle, the vehicle body frame structure includes main frames formed by coupling main tubes extending rearwardly downward from a head pipe supporting a front wheel via a front fork to pivot frames supporting a rear fork by rear end portions of the pivot frames, and a rear frame in a rear of the main frames, the rear frame being formed of a fiber reinforced resin and supporting a seat. The rear frame includes upper side attaching portions attached to the main frames, a pair of left and right upper side portions linearly extending rearward from the upper side attaching portions, and a cross member laterally coupling the upper side portions to each other. The cross member includes a bulging portion bulging above the upper side portions.

Abstract: A rear frame is formed of a laminate that includes a plurality of carbon fiber layers laminated one on top of another and hardened and integrated with each other by a plastic. A different color layer having a color different from a color of the carbon fiber layers is disposed between the carbon fiber layers in the laminate. When a carbon fiber layer on the outside is lost by a piece of flying gravel and a lost portion reaches the different color layer, a surface of the different color layer is exposed from the lost portion. An exposed portion having the different color can be easily recognized from the outside. The appearance of the exposed portion allows arrival of a replacement time of the rear frame to be recognized. As a result, it is possible to enable easy visual recognition of an optimum replacement timing.

Abstract: To provide an engine side cover structure of a saddle type vehicle that can also cover the back side of a crankcase. An engine side cover structure of a saddle type vehicle includes a vehicle body frame arranged between a front wheel and a rear wheel; an engine including a crankcase, and a cylinder extending upward from the crankcase, the engine being supported by the vehicle body frame; and a side cover covering a side of the crankcase; where the side cover includes a cover main body that covers the side of the crankcase, and an extended portion that extends backward from the cover main body; and the cover main body is fixed to the crankcase, and the extended portion is fixed to the vehicle body frame.

Abstract: A handling performance is improved by a fuel tank fitting structure. A fuel tank is mounted to a vehicle body frame at three points: a first fixed section with a bolt and two second fixed sections with two bolts. A grommet provided in the first fixed section has an interference. Each of the second fixed sections has a fitting clearance between a collar and the grommet, and an axial clearance between the collar and the grommet. These clearances enable the grommet without an interference and the fuel tank to relatively movable to the vehicle body frame. The fuel tank and a vehicle body thus have different behaviors during cornering, thereby obtaining reduced inertial weight and light handling.
