The invention relates to a steering mechanism of a motorcycle. The steering mechanism is connected to a head tube of a frame unit and comprises a lower steering stem socket arranged in the upper end of the head tube in a sleeved mode, a steering rod provided with a positioning groove, an upper steering stem socket arranged on the steering rod, a steel ball set arranged between the upper steering stem socket and the lower steering stem socket, a sealing sleeve arranged above the upper steering stem socket, a positioning nut arranged above the sealing sleeve, a gasket embedded in the positioning groove, a fixed nut locked onto the steering rod, and a handle support connected to the steering rod, wherein the lower end of the connecting portion of the handle support is sleeved with a waterproof sleeve, and the lower end of the connecting portion of the handle support and the upper end of the head tube are shielded by the waterproof sleeve. By the adoption of the steering mechanism, it can be ensured that outside pollutants do not flow onto the steel ball set in the bearing portion of the head tube through the positioning groove in the steering rod above the fixed nut, or the sealing sleeve, or the positioning nut to cause damage to the steel ball set, outside pollutants flow to the outside of the head tube through the waterproof sleeve under the blocking of the waterproof sleeve to ensure the using function of the steel ball set, and then the using efficacy of the steering mechanism is improved.
