The utility model relates to a clip orbit mechanism of a toy motorcycle, which comprises a chassis, and at least a pair of enclasping wheels which are arranged at the bottom of the chassis of the toy motorcycle, can symmetrically enclasp the orbit of the toy motorcycle and run along the orbit. The clip orbit mechanism effectively ensures that the toy motorcycle is tightly combined with the orbit and runs at a high speed but cannot disorbit. A wheel frame is rotationally arranged on the chassis of the toy motorcycle, and a bolt lock of the wheel frame can cause two idler pulleys to outspread a proper angle, thereby facilitating the toy motorcycle to be enclasped on the orbit, and also avoiding the idler pulleys from breaking away the orbit. In racing, the clip orbit mechanism can effectively ensure the toy motorcycle to run at a high speed by enclasping the orbit stably, but cannot disorbit, so that the original toy motorcycle which runs in the orbit is changed to run by the way that the motorcycle enclaspes the orbit, the toy motorcycle can completely expose outside the orbit, thereby improving the racing speed and the enjoying effect. The strip-shaped orbit is adopted, thereby not only reducing the volume of the orbit, but also being capable of being made into various structural models, realizing various types of shuttling of the toy motorcycle, and improving the interest for playing.
