Race Tech Fork Springs kg/mm Spring Rate

Race Tech Hi-Performance fork springs are replacement motorcycle fork springs (also called front suspension springs) for dirt, dual sport, adventure and street bikes. They come in a wide range of spring rates, measured in kg/mm. You can match the rate to your rider weight, riding style and terrain. The right spring rate is the base for good handling and properly working suspension.

Key Features:

• Chrome silicon spring wire for strength and durability
• High stiffness-to-mass ratio, so each spring is light for its rate
• Shot-peened and heat-treated to resist fatigue
• Preset construction so the springs do not sack out over time
• Accurate, tested spring rates for consistent, predictable fork action
• Wide selection of rates, lengths and diameters for dirt, street and cruiser forks

Race Tech has built hi-performance suspension components for motorcycles, ATVs, UTVs and snowmobiles for more than 36 years. Upgrading to the correct fork spring rate helps reduce bottoming, improves front-end support and gives a more controlled ride than a worn or mismatched stock spring. Some applications may need spacers to reach the preload you want. Race Tech springs are also commonly paired with Gold Valve cartridge emulators, which often require the matching spring length and rate.
