Abstract: In a saddle-type vehicle having at least three wheels, a tilt angle sensor layout structure is provided which ensures that a tilt angle sensor is minimally influenced by a centrifugal force or vibration of a vehicle body while the vehicle is turned, and the tilt angle sensor is protected against flying stones and the like. The vehicle includes an engine, and a fuel injection system for supplying fuel from a fuel tank to the engine, with a steering mechanism including a steering shaft provided on the front side of the vehicle body. A plurality of frame members constituting the vehicle body frame supporting the steering mechanism are connected in the shape of a frame loop in vehicle side view, and the tilt angle sensor for detecting the tilt angle in the left-right direction of the vehicle body is attached to the loop-shaped portion of the vehicle body frame.

Abstract: A front carrier includes an outer frame pipe surrounding the periphery, and a cross pipe and a back-and-forth member which are provided inside the outer frame pipe. A front side portion of the outer frame pipe is lowered at a one-step to form a stepped bottom portion. The back-and-forth member is disposed to extend obliquely downwardly from the cross pipe toward the stepped bottom portion. In addition, the widthwise inside portion of the rear side portion is bent to be forward to form an end side portion, which is joined to the cross pipe to be flush with the back-and-forth member. Thus, a cargo support surface formed by the cross pipe, the back-and-forth member and the end side portion is surrounded by an outer frame portion higher at a one-step than the cargo support. Part of the outer frame portion is allowed to serve as a cargo stopper for the cargo.

Abstract: An engine accessory layout structure for a vehicle by which engine accessories are laid out near the engine without trouble. The structure includes a throttle valve disposed in the periphery of an engine, and an engine accessory laid out at an upper portion of an engine and a lower portion of a seat. A heat guard is provided which is disposed on the upper side of the engine so as to separate the engine and a fuel piping from each other. The engine accessory is mounted onto an upper portion of the heat guard. The heat guard also protects the throttle valve.

Abstract: A body cover being formed by joining together a plurality of cover members including a maintenance cover which is detachably disposed on the side of the power unit. A pedal which is actuated by an individual operating the vehicle wherein the overall body frame is covered without modifying the structure and arrangement of the pedal. A suspension system wherein a swing arm type or an independent suspension type may be used in the vehicle. A light structure for a tail light wherein attaching lighting components such as a light emitting section are attached to a substrate formed in part of a lid of a utility box attached to a rear part of a vehicle. The lighting components such as the substrate are directly assembled in the concave section, and a lens is attached to the concave section by welding.

Abstract: A frame structure provided for a body frame that can be used in common to vehicles with different types of rear suspensions. The frame structure includes a sub-frame assembly for an independent suspension type rear suspension that can be mounted to a body frame by using pivot brackets for supporting a swing arm provided in the body frame, and also using an upper mount for supporting a rear cushion provided in the body frame.

Abstract: A rear fender mounting structure includes features for simplifying the assembly of a rear fender, sub-frame, and grab rails to a rear frame of a motorcycle. The sub-frame has brackets welded onto it. The brackets include holes with protruding collars defining the holes. The rear fender has holes lined with rubber bushings. The protruding collars are fitted into the rubber bushings. The rear fender includes a bracket which is hooked over a crossbar of the motorcycle frame. The fender is then lifted from its rear end, by pivoting the bracket about the crossbar. When alignment occurs between the bracket holes and holes in the rear frame, linkage plates with bolts extending therefrom, are employed. The bolts are passed through the aligned holes. Next, holes in the grab rails can be easily aligned with the ends of the bolts. Nuts are used to secure the arrangement.

Abstract: Seat rails and pivot frames are easily attached to a main frame of a motorcycle. Pivot frames and seat rails are connected to the sides of a rear end portion of a main frame in the form of a round pipe. Upper ends of the pivot frames and front ends of the seat rails are held against the sides of the rear end portion of the main frame such that their attachment axes L1, L2 are substantially aligned with an axis LO of the main frame and the upper ends and the front ends are staggered longitudinally in an overlapping relationship as viewed in a side elevation. The upper ends and the front ends are then welded to the main frame along continuous welding lines.
