Standard Progressive Suspension Spring (manufacturer part number: 11-1527) — a fork spring designed for roadsters looking to achieve a more consistent behaviour without altering the original geometry. Designed with progressive winding, it offers a soft initial phase for increased comfort in the city and over small imperfections, then progressively stiffens to limit bottoming out during heavy compressions.

• Fork tube diameter: 39.00 mm (1.54")
• Colour / finish: Black
• Supplied with a 3" PVC spacer for a clean and precise installation
• Made in the USA by Progressive Suspension

This spring improves road handling and fork endurance in road use, providing a more progressive response to compression without stiffening the initial part of the travel. Ideal for riders seeking more comfort in daily use while maintaining steering precision on winding roads.
