Saddle-riding vehicle provided with a frame having reduced stiffness against yaw movements

Abstract

The present invention relates to a saddle-riding vehicle, preferably an endurance-type vehicle. The vehicle comprises a steering tube to which a steering assembly that controls a front wheel is rotatingly connected. The vehicle comprises a frame comprising a central part () to which is hinged a first end (A) of a fork () which also comprises a second end (B) rotatingly connected to a rear wheel (). This frame also comprises a front part () extending between the steering tube () and said central part (), wherein this front part () comprises a first frame side (A) and a second frame side (B) separated in the direction of the width of the vehicle and made of a first metallic material. The vehicle according to the invention is characterised in that it comprises at least a pair of connecting plates (A-B) wherein a first plate (A) connects said engine assembly () to said first frame side (A) and a second plate (B) that connects said engine assembly () to said second frame side (B). These plates (A-B) are made of a second metallic material having a modulus of elasticity lower than that of said first material constituting said frame sides (A,B) of said front part () of the frame ().
