When the weather is cold, will motorcycles exhaust hot air from the exhaust pipe like cars?

Yes, because gasoline combustion needs oxygen, which is generally 1:7, and oxygen is absorbed from the air, which contains water. After combustion, water passes through high temperature in the cylinder to form steam, and only when the temperature is lower than a certain level can the naked eye see the steam. So motorcycle exhaust can be seen in winter, and there is a drain under the muffler. As long as the car burns well, it will drip from there unless the sewer is blocked.
