Function and use

The shock absorber uses emulsion damping technology, where gas pressure and oil are combined in a separate space to achieve a uniform damping effect. The thread-adjustable spring preload allows for individual adjustment to different driving conditions and rider weight. The linear spring rate ensures a constant spring force over the entire stroke.

The use of aluminum and steel ensures high stability and low weight. The internal reservoir position contributes to the compact design and protects the damper components from external influences. The extended length of 360mm meets the Triumph Street Twin rear suspension requirements.

Summary

The YSS gas pressure emulsion shock absorber is a suitable component for the rear suspension of the Triumph Street Twin. It offers manually adjustable spring preload, robust construction and a proven damping method. The combination of material quality and technical design supports reliable chassis performance.
