Motocross is one of the most challenging modern sports, and it provides an exhilarating experience to many two-wheeler enthusiasts of all ages worldwide. Motocross and dirt bikes are immediately recognizable for an aggressive stance, high ground clearance, narrow and rugged tires, and some other cues. These bikes feature great off-road ability, with motors producing high torque for improved performance on demanding motocross tracks or off-road routes. However, the top shape of the engine, including valves and valvetrain parts, is mandatory to ensure good performance and safety.
The intake and exhaust valves control the amount of the fuel-air mixture entering the engine and the flow of the burnt gases leaving it after combustion. The shape of the valves resembles a mushroom with a head and long stem. The stem runs in a valve guide to ensure the precision and effectiveness of operation. As the valves are subject to stresses and huge temperatures caused by combustion, they are prone to wear and even can be ruined under some conditions. You can replace them or upgrade the system with aftermarket valves which feature improved characteristics. In our online store, we have a large selection of premium motocross/dirt bike valves and valvetrain parts designed by top-ranked companies and offered at an affordable price.
