Progressive Suspension PS1144 Fork springsRef : PRSU00163A / PS1144

Progressive Suspension - Front fork springs (manufacturer part no. 11-1144). Replacement springs with progressive winding designed to provide a softer initial response while offering increased resistance at the end of the stroke, thereby reducing the risk of bottoming out during severe compressions. Made in the USA, they maintain the original geometry of the fork to preserve chassis behaviour.

• Outer diameter: 37.00 mm (1.45")
• Length: 394.00 mm (15.50")
• Spring rate: 0.71 – 1.16 kg/mm (40 – 65 lb/in)
• Contents: Pair of springs + 10.00" spacer
• Manufacturer reference: 11-1144

These springs are aimed at riders seeking a compromise between comfort and road holding: better absorption of small imperfections thanks to the initial softness, and more progression when the fork works deeply. Ideal for touring, trails/adventure, roadsters, and sports bikes that retain the original fork configuration.

Examples of compatible motorcycles (for reference only): TRIUMPH ROCKET III 2300 Touring (2010), KAWASAKI VN 1600 Vulcan Classic (2008), SUZUKI DL 1000 V-Strom (2007). A simple choice to restore or enhance front behaviour without altering the original geometry.
