PROGRESSIVE SUSPENSION — Reinforced Fork Spring Kit (Ref. 11-1552)

This progressive rate fork spring kit is designed for riders seeking a firmer response and a more neutral front end behaviour without changing the cartridges. Designed to reduce the dive felt during braking and stabilise the front end, these springs include preload spacers — including a 3.00" spacer provided — to adjust the ride height and preload according to the rider and load.

• Outer diameter: 39.00 mm (1.54")
• Length: 470.00 mm (18.50")
• Spring rate: 0.79 - 1.27 kg/mm (44 - 71 lb/in)
• Contents: pair of springs + preload spacers (incl. 3.00" spacer)
• Manufacturer reference: 11-1552

Suitable for Vintage/Classic, Enduro, Roadster, and Touring universes, these springs are ideal for heavier riders or those looking for a more dynamic fork feel. They are compatible with many machines (e.g. certain Harley-Davidson Sportster and Street models, KTM Freeride), but installation will depend on your fork's specifications — check the length and diameter before installation.

Manufactured by PROGRESSIVE SUSPENSION, these springs offer a simple and cost-effective option to refine front-end handling without a complete fork overhaul.
