Motorcycle Sprocket Chain characteristics
Structural integrity under extreme conditions
The top 20CrMnTi carburizing steel is selected to replace ordinary A3 or 45# steel, and the carbon content is controlled between 0.17-0.23. Compared with traditional materials, the overall toughness is improved by 40%, effectively preventing the risk of gear fracture during high torque acceleration and ensuring structural integrity under extreme working conditions.
Eliminate abnormal noise when driving at high speed
The automatic CNC gear hobbing machine is adopted, and the tolerance of tooth profile is strictly controlled within 0.1mm. The high-precision meshing degree increases the transmission efficiency to more than 98%, while reducing the chain beating caused by the meshing gap, and eliminating the abnormal noise during high-speed driving from the source.
Absorb pavement impact to prevent brittle fracture
The teeth are treated by high-frequency induction hardening with a depth of 1.5 mm-2.0mm, and the surface hardness reaches HRC 58-62, while the center maintains the toughness of HRC 30-40. This “outer hard inner tough” structure not only improves the wear resistance by 3 times, but also absorbs the impact of the road surface and prevents brittle fracture.
Four-sided riveting process to solve the hidden danger of pin shaft shedding
The chain pin adopts the advanced four-sided riveting process and cooperates with the 30CrMnTi pin material to increase the tensile strength to 38kN (for 520 specifications). This structure completely solves the hidden danger of the pin shaft falling off in the severe bump of the chain, and the impact resistance is about 25% better than the industry standard ISO 10190.
Pre-stretching process eliminates initial extension
All factory chains are pre-stretched by 1/3 breaking load, which eliminates the initial physical extension of the material in advance. After loading, the “run-in period” chain elongation is reduced by 80%, and users do not need to adjust the chain tension frequently within the first 1000 kilometers.
Self-lubricating Technology of Solid Oil Seal
Equipped with high quality X-Ring or O-Ring sealing ring, and vacuum high temperature grease between the pin and sleeve. This not only stops the intrusion of sediment, but also ensures continuous lubrication and the smooth operation of the chain system for more than 20,000km in the absence of external maintenance.

Motorcycle Sprocket Chain comparison point
Compared with the common 45# steel sprocket in the market, the biggest advantage of this motorcycle sprocket chain lies in the deep combination of material and heat treatment process. Ordinary products are often only treated with surface blackening or overall quenching and tempering (HRC 35 or so) in order to save costs. Although the hardness is uniform, the wear resistance is extremely poor. This product uses 20CrMnTi with the tooth surface high frequency quenching, under the premise of ensuring that the tooth root does not break, the tooth surface wear life extended by more than 2.5 times. In addition, the matching chain adopts solid sleeve technology, which has better roundness and tighter meshing with the sprocket than the rolled sleeve, thus greatly reducing the running noise.
Eliminate the early elongation and loosening of the chain
In view of the problem that the low-end chain on the market becomes loose within one week after loading, this product eliminates the “initial creep” of metal materials through the high-load pre-stretching process before leaving the factory, and solves the trouble that users need to frequently go to the repair shop to adjust the tightness as soon as they change the new chain.
Resolve tooth tip wear into a “hook”
In view of the problem that the sprocket tooth tip is rapidly worn and sharpened due to high-intensity riding, which leads to tooth skipping and de-chaining, this product increases the depth of the hardened layer of the tooth surface to more than 1.5mm, even under the harsh working conditions of mud and sand mixing, it can keep the tooth shape intact and solve the potential safety hazard caused by gear wear.
Eliminate the howling sound of high-speed driving
In view of the problem that the poor concentricity of the sprocket causes periodic noise during high-speed driving, this product introduces the inner hole and mounting hole of the fully automatic numerical control precision lathe, and the concentricity tolerance is controlled within 0.1mm, thus solving the driving experience problem of large vibration and harsh noise of the transmission system.
Motorcycle Sprocket Chain for Crowd
Urban commuter and takeaway distribution groups
Such users use motorcycles frequently every day, with long mileage and frequent start and stop. The high wear resistance and pre-stretching technology of this product greatly reduces the frequency of daily adjustment of the chain and replacement of accessories, saving them valuable maintenance time and maintenance costs.
Любители дальних мотопутешествий
For users who often ride across provinces or borders, they are faced with changeable road environment (rain, sediment). The O-Ring/X-Ring seal chain of this product has excellent dustproof and waterproof performance, and the alloy steel sprocket has strong fatigue resistance, which can ensure that the transmission system will not drop the chain during the journey of thousands of kilometers.
Motorcycle repair and modification shop
For the B- side repair shop that directly serves the owner of the terminal, the adaptability and convenience of installation of the product are very important. This series covers 428/520/530 and other mainstream specifications, and the tolerance is accurate, no need to polish or force knock during installation, can help technicians to quickly complete the replacement, improve customer satisfaction.
cross-country and forest road riding players
The off-road environment has a great impact on the transmission system. The high-toughness core of this product is designed to withstand the instantaneous huge torque when landing on a flying slope, prevent the sprocket from breaking teeth or chain breaking, and ensure the safety of riders under extreme sports. It is an ideal upgrade for high-performance off-road motorcycles.
Motorcycle Sprocket Chain instructions
Chain tightness inspection and adjustment
After installation or regular inspection, the ladder should be supported and moved up and down in the middle of the lower chain. The standard free clearance should be controlled between 20mm-30mm. Too tight will accelerate wear and may damage the output shaft oil seal, too loose there is a risk of chain off.
Precautions for the initial run-in period
The newly replaced motorcycle sprocket chain requires a running-in period of about 300-500 kilometers. During this period, it is recommended to avoid rapid acceleration and violent downshifting, so that the sprocket tooth surface and the chain roller gradually form the best fit surface, which helps to extend the subsequent service life.
Standard operation for lubrication and maintenance
It is recommended to clean and lubricate every 500-800 kilometers. Use special chain cleaning agent to remove old oil sludge, wipe dry and then spray chain wax or lubricating oil. Note that the nozzle should be sprayed to the gap between the chain roller and the chain plate, and wait for 15 minutes for grease to penetrate before riding.
Visual inspection of sprocket wear
Check the sprocket tooth profile every 3000 kilometers. If the tooth tip becomes sharp (serrated) or there is obvious depression on the side of the tooth valley, it indicates that the wear has exceeded the limit. At this time, it is strictly forbidden to replace only the chain. The sprocket chain must be replaced in complete sets, otherwise the old sprocket will quickly damage the new chain.
