There is no essential difference between the trademarks of YAMAHA musical instruments and Yamaha motorcycles, except that the colors of the trademarks are slightly different on different models of products. Yamaha merchants are all composed of three superimposed tuning forks (similar to Y letters) and Yamaha characters, and they will use different logos on different products or at different times, sometimes with graphics and sometimes with characters, and they will be different in different periods. If carefully distinguished, the middle of M in Yamaha motorcycle trademark is the bottom, and the middle of M in Yamaha letters of musical instruments or other products is not the bottom.
