YSS Piston Rod for Motorcycle Shock Absorbers – Precision and Reliable Performance

Package Contents

• Hard-chrome-plated piston rod (1 piece): 12 mm outer diameter, 85 mm length, M10 / M12 connection threads, 4.5 mm longitudinal bore and cross-drilled oil passage.
• Rebound adjustment needle: Slender metal needle inside the longitudinal bore, with a tapered tip for adjusting the piston oil bypass.
• Internal O-rings: Sealing rings on the adjustment needle to help seal the oil passage.
• Retaining or pressure components: Depending on the 2A83-series variant, a retaining circlip/snap ring or a return spring to locate or preload the adjustment needle.

YSS piston rods for motorcycle shock absorbers are high-quality replacement components designed for the maintenance, repair and refurbishment of motorcycle suspension systems. Their precise manufacturing and accurate dimensions support reliable shock absorber operation and proper component fitment.

Essential Function Within the Shock Absorber

The piston rod is a key component of a hydraulic shock absorber. It connects the internal damping piston to the external mounting assembly and transmits the forces generated during suspension compression and rebound. As the suspension moves, the piston rod travels through the shock absorber’s guide and sealing system, allowing the damping piston to move in a controlled manner inside the damper body.

A precisely manufactured piston rod helps ensure smooth movement and supports the correct operation of the sealing and guiding components. This contributes to maintaining the intended damping characteristics and consistent suspension performance.

Precision Manufacturing for Reliable Damper Operation

YSS piston rods are designed for use in motorcycle shock absorbers and feature carefully manufactured surfaces and accurate dimensions. These characteristics are particularly important because the piston rod is continuously exposed to movement and mechanical stress during riding.

Depending on the version, YSS piston rods are available in various diameters, lengths and thread configurations, providing suitable replacement options for different shock absorber designs.

Ideal for Shock Absorber Maintenance and Repair

During shock absorber servicing or refurbishment, replacing a damaged or worn piston rod may be necessary. A correctly specified YSS replacement piston rod allows professional repair and helps restore the shock absorber’s intended functionality.
