Progressive Suspension Front Fork Springs 37.00 mm - Model 11-1521

Upgrade your motorcycle’s front suspension with the Progressive Suspension Front Fork Springs, part number 11-1521. Designed with a progressive winding pattern, these springs provide a smooth initial ride by offering a softer spring rate at the start of compression. This results in a more comfortable and plush ride quality, especially over uneven terrain. As the spring compresses further, the increased resistance helps prevent bottoming out, maintaining stability and control during aggressive riding or heavy loads. Made in the U.S.A., these springs are engineered to improve handling while preserving the OEM geometry of your motorcycle’s front fork system, ensuring compatibility and optimal performance. Installation is straightforward, and the springs are crafted from durable materials to withstand demanding riding conditions, offering long-lasting reliability and consistent performance.
