Upgrade front-end performance with the Race Tech Fork Spring 0.50 kg/mm, manufacturer part number FRSP 444750. Designed to provide a more appropriate spring rate for performance-focused riders, this high-quality fork spring helps improve handling balance, rider confidence, and predictability. Sportbikes and motocross motorcycles are often undersprung for the rider’s weight and riding style, which can contribute to an unbalanced feel. Selecting the proper Race Tech spring rate is an important first step toward achieving more controlled suspension performance.
Made from chrome silicon wire, the Race Tech FRSP 444750 offers a high stiffness-to-mass ratio while maintaining reliable performance under demanding riding conditions. The spring is shot-peened and heat treated for enhanced durability, accurate rates, and resistance to sacking out over time. Its 0.50 kg/mm spring rate is suited to applications requiring additional fork support and consistent response.
Fitment includes the 2007–2012 Kawasaki KX450F, the 2005–2007 Kawasaki KX250, and the 2005 Yamaha YZ125. Confirm the motorcycle model year, existing suspension setup, rider weight, and intended use before installation to ensure the selected rate is appropriate. The Race Tech Fork Spring FRSP 444750 is a dependable replacement or suspension upgrade for riders seeking precise, repeatable fork performance.
