428-48T motorcycle Sprocket

Max Trading supplies high-performance 428-48T motorcycle sprockets. As a core transmission component connecting the engine and rear wheel, this product is made of top-grade 45# medium carbon steel and undergoes a precise professional heat treatment process, achieving a surface hardness of HRC25-30, significantly improving wear resistance while maintaining internal toughness. As a professional Motorcycle Sprocket Factory Supplier, we not only provide standard 48-tooth parts that precisely fit the 428-type chain, but also help global wholesalers gain a competitive edge in freight and quality through a substantial 15% purchase discount, flexible OEM/ODM customization services, and one-stop import and export logistics solutions.

1. Product Introduction & Core Role

The sprocket is a key link in the motorcycle power transmission system, connecting the engine output shaft and the chain to transfer power to the rear wheel and drive the vehicle forward. Its performance directly determines the smoothness of power output, the efficiency of energy transmission, and even the driving safety of the motorcycle.

During operation, the sprocket needs to withstand continuous torque loads from the engine, as well as friction and impact generated by high-speed meshing with the chain. In harsh working conditions such as uphill climbing, heavy load transportation, and off-road riding, the sprocket is prone to wear, deformation, or even fracture if its material and processing quality are insufficient. Therefore, a high-quality sprocket is an essential guarantee for the stable operation of the entire motorcycle.

2. Product Core Advantages

2.1 Premium Material Selection - 45 Medium Carbon Steel

The 428-48T motorcycle sprocket is crafted from 45 medium carbon steel, a material with balanced carbon content that avoids the brittleness of high-carbon steel and the insufficient strength of low-carbon steel. This material has a certain base strength without heat treatment, meeting the basic requirements of power transmission, and its mechanical properties are significantly enhanced after professional heat treatment.

2.2 Professional Heat Treatment Process - Balanced Strength & Wear Resistance

After undergoing precise heating and cooling heat treatment, the 45 steel sprocket achieves comprehensive performance improvement:

Surface Hardness Optimization: The surface hardness reaches HRC25-30, effectively resisting wear caused by long-term meshing with the chain, reducing tooth surface wear, and maintaining meshing accuracy.

Toughness Retention: While improving surface hardness, the internal toughness of the sprocket is retained, enabling it to withstand instantaneous impact and torque peaks during riding without breaking or deforming.

2.3 Adaptability to Diverse Working Conditions

Thanks to its balanced mechanical properties, this sprocket is suitable for various motorcycle types and usage scenarios, including:

• Daily commuter motorcycles for urban road riding
• Cargo motorcycles for heavy load transportation
• Off-road motorcycles for complex terrain riding
• Modified motorcycles pursuing stable power output
