There are many answers to the question Why is my motorbike smoking a lot depending on the color of the smoke and if this is accompanied by other symptoms that may indicate a certain mechanical problem. Sometimes it is simply the response of the machine to extreme climatic conditions. At OneHowTo we'll help you find explanations to the question Why is my motorbike smoking so much?.

Steps to follow:

If your bike is smoking a lot and the smoke is black or very dark, you may have a problem of poor carburetion. In this case, you will notice other symptoms of mechanical failure in your machine, such as the engine bogging down and even stopping while in motion. Visit your mechanic to fix your vehicle.


A problem in gasoline composition may be the cause of your bike smoking, if it is an intense white colour. This may be because the fuel is of poor quality or is contaminated. In general we recommend that you always buy quality products for your machine. Even though you spend more, you're extending the life of your bike.

It can also be because it is burning oil. The colour of the smoke is very dark grey if this is the case. To solve this problem, always use a quality lubricant and, if possible, regulate the oil pump as recommended by the manufacturer.


In any case, you should go to the mechanic if your bike has a lot of smoke. This professional can measure the gas contamination and if necessary, change the catalyst so the problem does not happen again.


If you live in an area where the temperature is very low, you should not worry if there is excessive white smoke, as this is the natural response of the machine under these circumstances. Of course, if the smoke is another colour or occurs with other symptoms that might indicate a failure, go to your mechanic as soon as possible.
