<p>PURPOSE:To improve operability, travel stability and durability or the like by setting the diameters and the tire breadths of front wheels smaller than those of rear wheels, and at the same time, adopting such a means as sets the mutual breadth between the front wheels narrower than that between the rear wheels, or the like. CONSTITUTION:The diameters d1 of a pair of front wheel 3 provided at the right and left of the front of a frame 2, and the breadths W1 of balloon tires furnished thereat, are respectively set smaller than the diameters D of a pair of rear wheels 4 provided at the right and left of the rear of the frame 2, and the breadths W of balloon tires furnished thereat. Also, the mutual breadth l2 between the pair of front wheels 3 is set narrower than the mutual breadth l3 between the pair of rear wheels 4. In addition, the breadth l1 between a pair of bar steps 16 provided at the right and left of the center portion of a body is arranged on the inner side than the breadth l2 at front wheels 3. Meanwhile, the outside edge at a front wheel 3 front fender which is not shown in the drawing, is arranged on the inner side than the outside of balloon tires, and at the same time, a tapered formation from the outermost portion toward the front is made.</p> |
