    • To place a muffler in a front area to make it suitable for an off-road motorcycle, A down frame extending downward obliquely from a head pipe ahead of an engine and a lower frame connected with its lower end, extending backward under the engine, are provided. A muffler is located in the vicinity of the joint between the down frame and the lower frame where its rear surface is curved forward in a convex pattern along the down frame and the lower frame. An exhaust pipe extending from a cylinder head is almost S-shaped as seen sideways and its forward curved portion and lower backward curved portion are vertically arranged with its lower end connected with a lower portion of the muffler.

    • A three-wheeled, motor-driven, pedal-started vehicle which comprises a tubular frame supporting the wheels in triangular relationship. A seat is provided on the frame covering a trunk or receptacle relative to which the seat is pivotable in order to uncover the trunk or receptacle. A motor and pedal arrangement is provided on the frame for driving one of the wheels. A kickstand is provided to elevate this wheel selectively from the ground to facilitate the starting of the vehicle without the need for driving the weight of the same. A demountable canopy is detachably connected to the tubular frame and provides a transparent shield for the driver of the vehicle. The seat is such as to be able to accommodate the driver and at least one passenger in side by side relationship. A steering arrangement is provided having a jog therein to accommodate the offset relationship of the driver to the central axis of the vehicle when a passenger is accommodated. This steering device is also provided with an offset in order to yield to impact forces. The rearmost wheels are mounted for pivotal displacement.
