Standard Progressive Suspension Spring (ref. 11-1567) — Fork spring designed for demanding touring and road bikes. Its progressive winding design offers a soft initial phase to absorb small bumps without transferring shocks, followed by a stiffness curve that reduces the risk of bottoming out during heavy compressions. Ideal for restoring comfort while maintaining the original geometry of the motorcycle.
These springs improve road holding and handling by optimizing the compression and rebound response of the fork, while preserving the original stance. They are particularly suitable for heavy road and custom trails equipped with 49 mm forks, providing better feedback at the handlebars without altering the geometry.
Common compatibilities: Harley-Davidson FLTRUSE2 Road Glide Ultra CVO (2016), FLHXSE Street Glide CVO (2016), FLHTKSE Electra Glide Ultra Limited CVO (2016) — check the tube diameter and the specifications of your fork before fitting.
