Chain 428h has the core selling points of low torsion resistance and high wear resistance, and can achieve 78 decibels of low noise and smooth operation with buffer sprocket. As a source manufacturer with a history of 33 years, Motomaxsfr has five physical production bases, excluding middlemen, providing overseas wholesalers with highly competitive ex-factory prices and stable batch delivery guarantee.
Chain 428h is the 1 high-performance motorcycle transmission chain made of high-strength alloy steel. It mainly transmits power through meshing with front and rear sprockets. It is widely used in the drive systems of leisure scooters and intelligent electric motorcycles.
The optimized chain pin shaft and sleeve fit tolerance is adopted, and the transmission noise is as low as 78 decibels when driving at 60 kilometers per hour, which greatly improves the quiet texture of the vehicle.
high-specification refined alloy steel materials are selected and precision heat treated to make the overall tensile strength exceed 20.6 kN, effectively preventing the chain from breaking during instantaneous acceleration.
the sleeve and the inner section are subjected to high-frequency quenching process, and the surface hardness reaches more than 60 Rockwell hardness, which greatly reduces the chain elongation rate and prolongs the maintenance cycle of the transmission system by 1 times.
Precision parts processing technology and special pre-stretching treatment reduce the frictional resistance between pitches, improve power transmission efficiency and reduce the power consumption of the vehicle.
the built-in customized rubber sealing ring can permanently lock the internal grease and block the entry of external sediment, and can still maintain excellent lubrication under bad road conditions.
strictly implement the international standard pitch manufacturing, which can perfectly adapt to the mainstream 428 specifications buffer sprocket in the market, and greatly reduce the cost of model adaptation and after-sales exchange of wholesalers.
| Parameter Items | Technical Specifications and Indicators |
| Product Keywords | Chain 428h |
| Pitch | 12.70 mm |
| Roller diameter | 8.51 mm |
| Inner section inner width | 7.85 mm |
| Pin diameter | 4.50 mm |
| Chain plate thickness | 2.03 mm |
| Average tensile strength | 22.5 kN |
| Weight per meter | 0.95 kg |
| Applicable vehicle speed | 60 to 120 kilometers per hour |
| Matching motor power | 3 to 8 kilowatts |
suitable for pedal electric motorcycle manufacturers that focus on urban commuting and have strict requirements on driving noise. The operation performance as low as 78 decibels can perfectly fit the high-end positioning of the whole vehicle.
suitable for wholesalers who need to purchase universal transmission kits in large quantities. The chain has high standards and can be widely adapted to a variety of models, which helps to reduce the backlog of inventory categories.
For sports cars equipped with 3 to 8 kW mid-power motors, the chain has strong impact resistance and low power consumption performance, which can effectively extend the vehicle’s cruising range.
suitable for professional repair channels that pay attention to wear resistance and long life of accessories, high-strength quality performance can greatly reduce the secondary repair rate of end car owners.
The inner and outer chain plates of this chain 428h are made of high-quality cold-rolled alloy steel strip, which has excellent ductility and fatigue strength. The pin shaft and roller parts are made of high-carbon chromium steel modified by trace elements, with advanced overall carburizing heat treatment process. This ensures that the core components of the chain have high toughness to absorb impact loads, and the appearance has extremely high hardness to resist abrasive wear, thereby ensuring the stability and safety of the overall structure.
Motomaxsfr provide comprehensive technical support for B2B customers. Pre-sales can provide accurate chain and buffer sprocket selection matching scheme according to the customer’s vehicle power and speed requirements; After-sales commitment to provide quality tracking for all factory batch orders. In case of non-human material defects, a team of professional engineers will quickly respond and provide replacement and replenishment services.
The expected service life of this chain 428h can reach more than 20000 kilometers under regular maintenance conditions. During use, it is recommended to check the chain tension every 1000 kilometers, and use a special chain lubricant for surface cleaning and lubrication to ensure that the transmission efficiency is maintained in the best condition.
