You may suddenly find that a motorcycle will not start, despite having enough battery and fuel. In these cases, the first step is to look for the cause in order to find the solution and for the motorcycle to function correctly again.



Most frequent causes why a motorcycle does not start

To find the reason why a motorcycle does not start, the first thing to do is to remain calm. Leave a couple of minutes and repeat the process calmly. Nerves are not a good ally.


If despite this the fault persists, it can seem disconcerting, especially if the motorcycle has the proper maintenance and revisions. Misuse of the vehicle can lead to unexpected failures, but bad luck and other uncontrollable factors also play a role.


It should be mentioned that, if the motorcycle starts and shuts down, or does not start at all, it is not a good idea to insist too much , since we can cause the engine to drown or the battery to wear out. The reasons why the motorcycle does not start can be the following:


The power cut button is not on

The red on / off switch is located on the right control of the motorcycle . This is responsible for turning off the motorcycle instantly and, when it is in the off position, makes starting impossible.


Whether it's accidentally rubbed or worn, it can be one of the simplest reasons why the bike won't start. Therefore, the first check that you should do is to verify that the power cut button is in the correct position, for which it is enough to press it several times and try to start the motorcycle when doing so.


Side leg problems

For safety reasons, the motorcycle will cut off the power if it detects that the kickstand is unfolded and there is a gear engaged when starting it . On the contrary, when the motorcycle is in neutral, this safety cut-out does not occur. In these situations it is important to verify that the leg is not responsible for not being able to start the motorcycle.


You can usually verify that the leg switch is broken or has come loose when you can start the bike by squeezing the clutch.


Disadvantages with the proximity key

If your motorcycle has a proximity key, certain inconveniences with this mechanism could cause you not to be able to start it. For example, when the battery is too low, it may not be detected by the motorcycle , causing it not to start.


Similarly, the frequency inhibitors found in some security zones can interfere between the communication of the proximity key and the motorcycle, which can also make it impossible to start it. In the first case, it will be enough to charge the battery and in the second, to push the motorcycle to another area. If you prefer, you can also use a physical key.


Damaged starter motor

Damage to the starter motor can also cause a motorcycle to fail to start the system normally. In these cases the start button may sound, but if there is not even power it will not make any sound . This may be the problem if the bike won't start and has a battery.


Reservoir breather obstruction

The fuel cap needs its vents to allow the entry of air and exit of gases. When there is an obstruction and this is not possible, the gasoline cannot circulate and a vacuum condition appears, which can prevent the engine from running.


These clogs are relatively common and are often caused by rust or dust. Therefore, if you have doubts about why the motorcycle does not start, it is recommended that you check that the tank vents are clean. If this is the problem, it should be fixed by opening the cap. A helpful tip is to clean the clog with a cloth soaked in lubricant.


Keep all these points in mind if you have trouble starting your motorcycle even though it has a battery and fuel. If despite all the information you can not get it to start normally, make an appointment at the workshop and avoid risks.
