Introduced in the 1920s, scooters belong to one of the most unique means of transportation ever. Small and nimble, they are perfectly tailored to cope with the chaotic traffic of modern towns. They are usually more affordable than motorcycles, although there are rather large and powerful scooters that can attain high speeds. Like in any motor vehicle, the engine is the core of these two- or three-wheelers, and every motor component has to be in good shape to ensure smooth function. Besides the piston(s), cylinder(s), and crankshaft, any four-stroke motor has the valvetrain mechanism, and its performance is also crucial for engine operation.
Modern engines use poppet valves where a long stem runs in a guide while the valve is opening or closing. During their work, the valves have to withstand high temperatures and stresses caused by the combustion process and can deteriorate or even be ruined over time. If you're upgrading the motor for improved performance, consider installing stronger valves and springs, more robust and efficient than the stock ones. For a large choice of premium scooter valves and valvetrain parts, browse our virtual catalog: our products are designed to meet or exceed the main standards for the category and offered at reasonable prices.
