Abstract: An exhaust structure for a straddle-type vehicle includes a muffler having an outer tube constituting an outer circumferential member of the muffler; first and second separators defining expansion chambers in the outer tube; a body end member arranged at the downstream end of the outer tube; and glass wool provided on the inner circumference of the outer tube. The muffler further includes a resonator chamber provided in the most downstream portion of the muffler. The resonator chamber is formed by the outer tube, the body end member and the second separator situated closest to the body end member. The surroundings of the resonator chamber are surrounded by the glass wool. Such exhaust structure of a straddle-type vehicle is capable of taking measures against exhaust heat and exhaust sound even with a configuration where there is only one, single resonator chamber.

Abstract: A side cover structure for enhancing the external appearance and turning performance of a saddle-ride-type vehicle. A side cover structure of a saddle-ride-type vehicle includes a head pipe with a frame extending rearwardly from the head pipe. Side covers cover the frame from left and right sides. A bent portion is bent toward the outside in a vehicle width direction from a base portion and is formed on the side cover. An opening is formed in the base plate portion positioned in the vicinity of the bent portion.

Abstract: A rear seat for a saddle type vehicle that is readily adjustable without changing the position of a main seat to improve the riding comfort of the rear seat. A saddle type vehicle includes a head pipe, a main frame provided behind the head pipe and a seat rail extending to the rear of the main frame. A main seat is provided with a rear seat provided behind the main seat and formed as a separate member from the main seat. The rear seat is attached to a rear seat holding portion provided at a rear portion of the seat rail through a base plate for holding the rear seat thereon. The rear seat can be moved forwardly and rearwardly by making it possible for the base plate to be fixed at a plurality of positions in the forward and rearward direction with respect to the rear seat holding portion.

Abstract: A foot pedal structure for a saddle-type vehicle for preventing peripheral components in the periphery of a brake pedal from being damaged even though the brake pedal and the peripheral components are not widely spaced from each other. A brake pedal includes at least an arm extending in a longitudinal direction of the vehicle from a step support member and a pedal member mounted on a distal end of the arm and extending in a vehicle widthwise direction. An upward extension in the form of a plate member extends upwardly from a treading surface of the pedal member and is disposed on an inner end of the pedal member in the vehicle widthwise direction.

Abstract: An automatic transmission control device for a vehicle includes a gear change operation that is performed based on a throttle opening, a vehicle speed and an engine rotational speed. The automatic transmission control device also obtains a displacement of the throttle opening, determines whether the displacement falls within a predetermined range, and restricts a shift-up when the displacement exceeds the predetermined range.

Abstract: An automatic transmission control device of a vehicle performs a gear change operation based on a deceleration of the vehicle. The automatic transmission control device detects the deceleration of the vehicle and an engine rotational speed. The device also stores a peak value of the engine rotation speed during a period in which a vehicle travels with one predetermined gear step, and includes a relationship map showing the relationship between the deceleration and a shift-down rotational speed. The device performs an automatic shift-down when the engine rotational speed is lowered from the peak value by a predetermined rotational speed which is obtained from the map based on the deceleration.
