The invention discloses a warning scald-proof device for a motorcycle exhaust pipe. The warning scald-proof device comprises an exhaust pipe body and a warning scald-proof frame, wherein the warning scald-proof frame is arranged outside the exhaust pipe body in a sleeving manner; one end of the exhaust pipe body is connected with a motorcycle combustion chamber, and the other end of the exhaust pipe body leads to air; the warning scald-proof frame is connected with the exhaust pipe body through a support frame, and a light reflection layer is arranged on the surface of the warning scald-proof frame. By the above method, the motorcycle exhaust pipe is provided with the warning scald-proof device, the normal exhaust and heat dissipation of the exhaust pipe is ensured, the high temperature of the surface of the exhaust pipe body is effectively avoided to directly contact with a user, and the scalding accident is prevented. Meanwhile, the scald-proof device has a reflective warning effect, improves the markedness degree of the exhaust pipe at night or in dark environment, has high practicality, and is safer.
