428H-120L Motorcycle Chain

In a motorcycle's powertrain, the chain plays a crucial role in connecting engine power to the drive wheels. Max Trading's 428H-120L Motorcycle Chain is designed for riding environments that prioritize high reliability and low maintenance costs. We understand that even minor chain deviations under high-speed and heavy-load conditions can affect the overall riding quality. Therefore, the 428H-120L Motorcycle Chain undergoes rigorous multi-stage quality control during production to ensure that each link is resistant to breakage under extreme tension.

Technical Advantages and Materials Science

1. Reinforced 40Mn Alloy Steel

Our chains primarily utilize high-grade alloy steel such as 40Mn. By precisely controlling the chemical composition ratios of carbon, manganese, and silicon, the chain's resistance to fatigue failure is significantly enhanced. In actual tensile tests, this material exhibits excellent yield strength, ensuring structural stability under extreme loads.

2. Precision Heat Treatment

The pins and rollers of each 428H-120L Motorcycle Chain undergo deep hardening. This process gives the surface extremely high hardness to resist physical wear while maintaining the toughness of the core components to absorb impact energy during operation.

3. Multi-layer Corrosion Resistance

The chain surface is covered with a tough protective film that effectively isolates it from rainwater, mud, and chemical corrosion. Test data shows that, under the same climatic conditions, the corrosion resistance time of this product is more than twice that of the ordinary model.

Maintenance and Usage Recommendations

To keep your 428H-120L Motorcycle Chain in optimal working condition, we recommend following these guidelines:

Regular Cleaning: Use a specialized cleaner to remove dust and grease from the chain to prevent abrasive wear.

Timely Lubrication: After cleaning, apply chain oil promptly, ensuring the lubricant penetrates the gap between the rollers and pins.

Tension Check: Regularly check the chain sag to ensure it is within the manufacturer's specified range, avoiding abnormal wear caused by excessive looseness or tightness.

FAQ

Q1: What is the difference between the 428H and the standard 428 chain?

A1: "H" stands for Heavy Duty. Our 428H-120L Motorcycle Chain features thicker chain plates and stronger pins, capable of withstanding greater tensile loads than the standard version.

Q2: Do you offer wholesale discounts or OEM customization?

A2: Yes. Max Trading offers tiered discounts for bulk purchases. We also provide OEM customization services, including specific number of links, packaging design, and branding.

Q3: What is the typical delivery time for our products?

A3: Standard 428H-120L Motorcycle Chains typically ship within 7-15 business days; customized products take approximately 15-30 days depending on production requirements.
