Applicable car model: Steering damper for Vespa GTS GTV 250 300. Suitable for 8MM universal bearing connection handles. Normal installation requires a dedicated vehicle-specific shock absorber bracket. The product only includes the shock absorber (as shown in the picture). High Quality Material: The damper has a built-in high-precision damping cylinder, and the main body is made of high-strength 6061 aviation aluminum alloy, which is tear-resistant and torsion-resistant. Strong and durable. The surface is anodized to resist corrosion and enhance the appearance. The moving piston is made of composite materials to reduce friction resistance. Exquisite Craftsmanship: High-strength quenched hard shaft, surface electroplated with anti-rust hard chrome layer, hardness above HRC60, the material is finely ground, smooth and wear-resistant, increasing the service life of the damper. It uses pollution-free damping oil, is extremely insensitive to ambient temperature, and can work normally in the range of -40 to +100. Professional Design: 8MM universal bearing is used to connect the steering handlebar to transmit the damping force to the steering handlebar. The adjustment knob is used to adjust the required damping force according to road conditions or driving habits. The use of a complete damping system and speed-sensitive technology helps maintain control and reduce fatigue. Safety Guarantee: The built-in high-precision buffer cylinder prevents the damping force from being too harsh. In the high-end configuration, a precision one-way valve is integrated. When the vehicle is driving on complex roads, the one-way valve can sense the road conditions and actively intervene in the instantaneous severe vibration, thereby increasing the safety of the vehicle.
