*The engine chassis guard effectively prevents important parts such as the engine oil pan from being hit or scratched while driving the motorcycle, especially when passing over rough roads, speed bumps, or encountering raised obstacles. Because the engine oil pan is located in a relatively fragile position at the bottom of the motorcycle, if it is scratched or damaged, it may cause oil leakage, seriously affect the normal operation of the engine, or even cause the engine to be scrapped.

*During driving, foreign objects such as stones and branches on the road may fly off and hit the engine. The chassis guard provides physical protection for the engine, reducing the direct impact of these external objects on the engine and acting as a buffer barrier to reduce the risk of engine damage due to impact.

*During daily driving, mud kicked up by the wheels, muddy water on rainy and snowy days, chemicals on the road, etc. may corrode the exposed parts of the engine. The chassis guard prevents these corrosive substances from coming into contact with the engine, extending the service life of the engine.

* Flat Engine Undercarriage Guard optimizes airflow under the motorcycle, allowing air to flow more smoothly under the body, reducing air resistance. Reducing wind resistance not only improves the motorcycle's riding stability, but also improves fuel economy to some extent, allowing the motorcycle to travel longer distances with the same amount of fuel.

* For high-performance motorcycles like the , chassis guards support downforce at high speeds. As the air speed increases, the air pressure under the fender decreases, and the air pressure above the vehicle pushes the fender down to the ground, improving the motorcycle's stability and maneuverability at high speeds.
