If the spark plug is worn, it can cause difficulties when starting and accelerating. This is often the case, especially with older motorbikes. So if you can no longer start the engine without problems, it is time to check the spark plug. If it is defective, it needs to be replaced.
If it is only fouled, cleaning it may solve the problem.
As a rule, according to some manufacturers, the spark plug should be changed every 10,000 to 20,000 kilometres, depending on the type of motorbike and the riding style. It is important to use the spark plug type and size recommended by the manufacturer to ensure optimum performance and longevity and to prevent possible engine damage. You can find this information either in the owner's manual, the service data sheet or the workshop manual.
Here you will find spark plugs and suitable accessories for a wide range of models.
Our tip: It is never a bad idea to always have a spare spark plug at hand. However, it should be carried in a shockproof and waterproof container.
