Overview

Constructed from shot-peened, heat-treated chrome silicon steel, these springs offer a high stiffness-to-mass ratio for enhanced durability and reduced unsprung weight. They are engineered to maintain their rate within a ±2% tolerance, ensuring consistent performance.

Each spring is preset to maximize its lifespan and effectiveness. These springs are intended to upgrade the ride quality, handling, and braking performance of compatible motorcycles, making them a recommended first upgrade for serious performance riders.

Show original supplier description

These 0.90 kg/mm springs are manufactured to a ±2% rate tolerance, ensuring that suspension performance remains predictable and accurate under demanding conditions. Each spring is crafted from premium chrome silicon steel that has been heat-treated and shot-peened to increase durability and resistance to fatigue from repeated high-load cycles. The design prioritizes a high stiffness-to-mass ratio, which minimizes unsprung weight to enhance overall suspension agility and responsiveness. Installation of these springs may require specific knowledge of fork geometry and internal damping systems. As these are performance tuning components, professional installation is often recommended to ensure proper preload settings and alignment. Always consult the specific service manual for your motorcycle's fork type—whether damping rod or cartridge style—to confirm compatibility and proper installation procedure.
