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 (12) to which is hinged a first end (8A) of a fork (8) which also comprises a second end (8B) rotatingly connected to a rear wheel (4). This frame also comprises a front part (15) extending between the steering tube (11) and said central part (12), wherein this front part (15) comprises a first frame side (15A) and a second frame side (15B) 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 (16A-16B) wherein a first plate (16A) connects said engine assembly (2) to said first frame side (15A) and a second plate (16B) that connects said engine assembly (2) to said second frame side (15B). These plates (16A-16B) are made of a second metallic material having a modulus of elasticity lower than that of said first material constituting said frame sides (15A,15B) of said front part (15) of the frame (10).
