The replacement springs from PROGRESSIVE SUSPENSION have been specially developed for the front fork of the Harley Davidson Sportster. They are used to replace the original springs and help adapt the chassis to individual requirements.
The springs are part of the front fork and influence the suspension characteristics of the motorcycle. By replacing the springs, the spring stiffness can be adjusted to the driver's weight, load and driving style. This improves driving stability and comfort while driving.
The spring rate of 0.63 to 0.89 kg/mm allows for flexible adjustment to different requirements. The length of 470 mm and the outer diameter of 39 mm correspond to the specifications of the original front fork springs of the Harley Davidson Sportster.
PROGRESSIVE SUSPENSION uses high-quality materials and precise manufacturing techniques to ensure a long service life and reliable function of the springs. The replacement springs are corrosion-resistant and retain their properties even under demanding conditions.
