Abstract

The motorcycle is particularly for cross-country use, having the front telescopic fork (11) and the shaft of the rear wheel (A) joined by a straight beam (2) extended by a swing arm (1) supporting the latter shaft. The beam can be of triangular section and composed entirely of straight bars and form a frame. Drive can be taken via a double intermediate sprocket (B), coaxial with the swing arm spindle, from engine to rear wheel. The engine can be so mounted on the chassis as to not to affect its rigidity, and the swing arm can act directly on a horizontal damper.
