Here are some factors that can affect the top speed of a 125cc pit bike:
* Engine size: The larger the engine size, the faster the pit bike will be able to go.
* Terrain: Pit bikes are designed for off-road use, and their top speed will be affected by the terrain they are ridden on. On flat, smooth surfaces, pit bikes can reach their top speeds. However, on rough terrain, their speed will be limited by the traction they can get.
* Modifications: There are a number of modifications that can be made to a 125cc pit bike to increase its top speed. These modifications can include adding a bigger carburetor, a high-performance exhaust system, and a performance air filter.
It is important to note that riding a pit bike at high speeds can be dangerous. Pit bikes are not designed for high-speed riding, and they do not have the same safety features as motorcycles. If you are planning to ride a pit bike at high speeds, it is important to wear a helmet and other protective gear.
