A steering system of a saddle-ride type vehicle includes a front fork that includes a steering shaft at the upper end and supports a front wheel at the lower end, a steering arm that is attached to the steering shaft, a steering force transmit member that is turnably supported by a steering stem that is disposed in a body frame, and a steering system link that joins the steering arm and the steering force transmit member. The steering system link joins the steering arm and the steering force transmit member that is disposed rearward of the steering arm. A steering force detection sensor that detects a steering force transmitted to the steering shaft is disposed in the steering system link.
