Product Introduction

Xuanyu Springs is a professional provider of motorcycle suspension spring solutions. Our products are designed specifically for the unique dynamic characteristics of two-wheeled vehicles, serving as core components connecting the wheels and frame and managing riding feel. Motorcycle suspension springs not only need to support the vehicle's weight but also must provide precise support and rapid rebound control during high-speed cornering, emergency braking, and complex road conditions. This clearly transmits road information to the rider while effectively filtering out excessive impacts, ensuring confidence in handling, riding safety, and a comfortable experience.

We specialize in providing high-performance, high-reliability custom suspension spring solutions for a full range of vehicles, from urban commuter scooters to hardcore off-road rally bikes, and from sporty racing bikes to luxury cruisers.

ProductParameters

project	Core Explanation
wire diameter range	1-80mm
Adaptation type	Suitable for upright and inverted front forks as well as various rear suspension structures (double swingarm, single swingarm, etc.).
Stiffness characteristics	It offerslinearandprogressivestiffness designs to precisely match different riding styles and load requirements.
Material system	High-end materials: We use oil-quenched steel wire from well-known brands such asSWP-B andSWOSC-Vfor valve springs. With its ultra-high purity, uniform microstructure and excellent fatigue resistance, it meets the most demanding durability requirements. High-qualityalloy steelmaterials: Mature application ofdomestic high-grade oil-quenched and tempered spring steel wires such as 55CrSi, 60Si2MnA, and 50CrVA , with stable performance, excellent cost performance, and can fully cover the needs of mainstream vehicle models. Specialty material applications : We can provide lightweight composite material solutions such asstainless steel, high-damping alloys or GFRP (glass fiber reinforced plastic) according to your needs.
core technology	Presetting: Precisely pressurizes the finished springs to maintain high stability under working stress, effectively preventing loosening during use and ensuring consistent vehicle posture over the long term. Heat treatment and surface strengthening: A precise and controllable heat treatment process is adopted, supplemented byshot peening, to introduce beneficial compressive stress on the spring surface, which significantly improves its fatigue life, especially its ability to resist impact loads. Precision forming: Possesses mature cold and hot rolling forming capabilities, ensuring precise spring geometry and high batch consistency.

Core Advantages of Xuanyu Motorcycle Suspension Springs

1. Precise tuning and matching of dynamic performance

We have a deep understanding of motorcycle dynamics. We can provide differentiated stiffness, preload, and travel matching recommendations for different core needs, such as "cornering support for sports bikes," "impact resistance for off-road vehicles," and "comfortable vibration damping for cruisers." Through precise calculations and a rich tuning database, our springs are designed to help vehicles achieve the desired handling characteristics, making every cornering and recovery stable and predictable.

2. Durability engineering designed for harsh environments

Motorcycle suspension systems are directly exposed to sand, water, and drastic temperature changes. Our springs feature a dual protection system built througha high-pressure treatment process and a special surface coating. The high-pressure treatment ensures long-term stability of the internal stress of the spring, resisting performance degradation; while the superior surface treatment provides a robust barrier, effectively resisting corrosion and ensuring durability and reliability even in harsh environments.

3. Comprehensive material range and selection capabilities

We possess the industry's most comprehensive database of spring materials and their applications. From classic high-performance spring steels (such as 55CrSi and 50CrVA) to corrosion-resistant stainless steel series, and even cutting-edge GFRP composite materials, we can provide the most economical material selection solutions for different vehicle models and scenarios (such as street, off-road, and racing). This advantage of "multiple materials and complete varieties" ensures that we can accurately balance performance, cost, and weight targets, providing you with the most competitive solutions.
