Max trading, the motorcycle manufacture in China, utilizing the commuting scenarios of CG125 motorcycles and our own production technology experience, has continuously upgraded the CG125 motorcycle front shock absorber, reaching a triple improvement in "stability, comfort, and durability". The upgrade plan has undergone rigorous testing and real-vehicle verification to ensure compatibility with this model.
Optimization of core structure
Our factory has abandoned the traditional single damping design and adopted an independently optimized dual-adjustment damping structure. By precisely controlling the damping hole diameter of the CG125 motorcycle front shock absorber and optimizing the valve spring rigidity, we have expanded the damping adjustment range, making it suitable for different road conditions in cities and villages, while balancing driving comfort and driving stability. At the same time, our factory has upgraded the inner tube material of the CG125 motorcycle front shock absorber to high strength seamless steel tube, which has undergone precision cold rolling and quenching processes to strong its compressive and wear resistance, avoid deformation and wear hazards, and prolong its service life.
Upgrading of shock-absorbing medium and sealing system
Our factory uniformly adopts high-viscosity anti-wear shock-absorbing oil, which has undergone high and low temperature testing from -20℃ to 60℃, ensuring stable lubrication and front shock-absorbing effect for CG125 motorcycles under different temperatures, and eliminating temperature-induced leakage. We have upgraded the oil-resistant and high-temperature nitrile rubber sealing sleeve and paired it with a multi-layer dustproof structure to cut down internal wear and lower the oil leakage rate.
The CG125 motorcycle front shock absorber, when exposed to the outdoor environment for a long time, is prone to erosion from rainwater, dust, and sediment, which can lead to surface rusting and corrosion issues. Thus, it is necessary to strengthen protection through precision plating technology.
Three major processes in plating technology
The first pre-treatment process is the foundation of plating quality. Our factory thoroughly cleans components such as the front shock absorber outer cylinder and piston rod of CG125 motorcycles, and completes degreasing, rust removal, and phosphating treatment in sequence, forming a uniform phosphate coating to enhance the adhesion of the plating and prevent detachment.
Step 2: Core Coating: The CG125 motorcycle front shock absorber adopts a "cationic electrodeposition primer + electroplating/spraying" scheme. The cationic electrodeposition has a salt spray resistance of over 500 hours, the piston rod is plated with hard chrome (above HV800), and the outer cylinder is sprayed with plastic to fit the vehicle model. High-end models can be provided with a DLC coating.
Post-treatment: The plating layer undergoes curing, cooling, and polishing to ensure smooth and even adhesion. Testing: Samples are taken for thickness (8-12μm), adhesion (in accordance with GB/T 13913-2008 standard), and corrosion resistance. Only qualified samples are permitted to proceed to the next stage.
Covering the CG125 series models from mainstream brands such as Wuyang Honda, Sundiro Honda, Zongshen, Lifan, Loncin, and Haojue,
Specifically, it can be matched with corresponding vehicle models according to the CG125 motorcycle front shock absorber installation dimensions and interface specifications.

1.Our factory has introduced automatic dynamic balance testing equipment to test each batch of finished shock absorbers, ensuring no abnormal vibration and enhancing the smoothness of the ride. Unqualified products are strictly prohibited from leaving the factory.
2.Our factory strictly controls CG125 front shock absorber quality. Equipped with a complete production system, upgraded technology and rigorous QC, each product balances performance, quality and adaptability—guaranteeing reliable handling and reflecting our professionalism.
1.The CG125 front shock absorber is divided into left and right parts. During installation, it is necessary to correspond to the left and right connecting seats of the frame and strictly avoid installing them reversely (some models have left and right marks, which need to be referenced). Guarantee that the upper and lower mounting holes of the shock absorber are consistent with the mounting holes of the frame and steering knuckle.
2.Use a torque wrench and apply the torque specified in the vehicle manual (typically 25-35N·m). Always follow the tightening sequence of "positioning first, then tightening" to ensure uniform stress distribution.
3.Clean the shock absorber oil seal lip; a light oil coat avoids leaks. Make sure that rubber components are correctly positioned and undamaged. For shock absorbers featuring tapered rubber pads, a backing plate is essential to maintain stable pressure.
4.For the oil-filled shock absorber, it is necessary to fill it with CG125 dedicated shock absorber oil (generally 10W or 15W). The filling amount must strictly follow the manual, and the oil volume on both sides must be consistent. After filling, press the piston rod to bleed air, guarantee smooth movement, then tighten the upper cover to prevent oil leakage.
