As a motorcycle enthusiast, I have always been fascinated by the performance and power of my 125cc Gy6 engine. However, after some time of riding and pushing my bike to its limits, I realized that there was still room for improvement.

Moreover, installing a big bore kit also improves the overall reliability and longevity of the engine. This is because the larger cylinder allows for better cooling and less strain on individual components. As a result, there is less wear and tear on the engine, leading
