The Race Tech Fork Spring 0.44 kg/mm, manufacturer part number FRSP 444744 and vendor part number 200-444744, is designed to help improve motorcycle handling, balance, and suspension predictability. Selecting the correct fork spring rate is an important step in achieving controlled suspension performance, particularly for sport and motocross motorcycles that may be undersprung for the rider’s weight and riding style.
Manufactured by Race Tech from high-quality chrome silicon wire, this fork spring delivers a high stiffness-to-mass ratio while maintaining consistent performance. The spring is shot-peened and heat treated for enhanced durability, accurate spring rates, and resistance to sagging or “sacking out” over time. Its 0.44 kg/mm rate is suited for riders and applications requiring dependable front-fork support and improved chassis balance.
This Race Tech fork spring fits the 2007–2012 Kawasaki KX450F, the 2005–2007 Kawasaki KX250, and the 2005 Yamaha YZ125. Verify the motorcycle model, year, and required spring rate before installation. The spring is supplied as a suspension replacement component for compatible front-fork applications.
