Abstract: A saddle riding type vehicle including a main body extending along a longitudinal axis and having a front part, a tail part and a central part interposed between the front part and the tail part, at least one front wheel and at least one rear wheel, a motor operatively connected to at least one of the wheels, a system mounted on the main body for reducing a collision risk and comprising at least one active radar reflector, where the collision risk reduction system allows the radar visibility of the vehicle to be increased as a radar target, i.e. increasing its equivalent radar cross section, in order to reduce the risk of the vehicle being involved in a collision with another vehicle equipped with automotive radar which, in an operating condition and during operation, approaches the vehicle.
