Race Tech Fork Spring 0.40kg for Kawasaki KX450F and Yamaha YZ125

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.

Constructed from high-quality chrome silicon wire, this spring offers exceptional durability and consistent performance.

Shot-peened and heat-treated, the spring resists sacking-out and maintains its rate over time, providing reliable responsiveness during demanding rides. Proper spring selection is crucial for balanced handling and predictability, especially on off-road bikes that are often under-sprung for the rider's weight and riding style. Race Tech offers over 500 high-performance springs, ensuring you'll find a perfect match for your setup. Installation of this spring can significantly enhance your bike's suspension feel, reducing bottoming out and improving overall ride quality.
