Product Introduction
Product features
▲ Low center of gravity, large high-efficiency cooling head, reducing the vehicle's center of gravity for smoother driving dynamics. The laser-patterned red anodization treatment on the cooling head creates a striking red-black appearance, exuding a strong sense of performance. The detachable aluminum alloy hemisphere-shaped TURBO combustion chamber features a red O-ring on the bottom edge, designed to reduce engine vibrations and provide excellent dust resistance.
