The drive belt transmits engine power to the wheel.

I see!
Now I know the thing that connects something like a disc on the engine side and the one on the wheel side is the drive belt.

By the way, what looks like a disc is called "pulley" and it has a structure like this!

Wow, this is how it's constructed!
Here, let's see how the pulleys and drive belt work.

When the scooter goes at a low speed, the drive pulley on the engine side has a small diameter while the driven pulley on the wheel side has a large diameter. As the engine speed goes up, the diameter of the drive pulley becomes large while the diameter of the driven pulley becomes small, increasing the vehicle speed.

I see... Wow, this is how they work!
Now I see the drive belt is such an important part!

However, when you continue using the drive belt, it will get worn and deteriorated. Eventually, the engine power cannot be transmitted to the wheel smoothly!

Wah! Is this what will happen?
Yes, it is! In addition, it might gets hard to ride up the hill or lower fuel economy!

If you continue using this, it will break off and you couldn't ride any farther.

Oh, no! I don't like that!
![Cub](../images/maintenance/character_f03.jpg)
In order to avoid those situations, the drive belt needs periodic maintenance! Right? Doctor?
That's right!
Also, don't forget to replace it regularly!
