The first step to great handling and predictability is selecting proper spring rates. With over 500 Hi-Performance Springs to choose from, Race Tech is almost guaranteed to have the spring you need. Sportbikes are generally under-sprung for the average rider, causing the bike to be unbalanced and unpredictable.
Upgrade your motorcycle's handling with the Race Tech Fork Spring designed for Kawasaki KX450F, KX250, and Yamaha YZ125 models. Crafted from high-quality chrome silicon wire, this spring offers exceptional durability and performance. Its high stiffness to mass ratio ensures your bike remains balanced and predictable, even under aggressive riding conditions. Proper spring rates are essential for optimal suspension performance, and this spring is engineered to provide precise control and stability. Shot-peened and heat-treated, the spring resists sacking out and maintains consistent performance over time. Whether you're a competitive rider or a serious enthusiast, selecting the right spring can dramatically improve your bike's responsiveness and ride quality. This spring
