Our products
The 420H chain is the 1 reinforced motorcycle transmission component designed for high-load environments. It is manufactured from high-quality alloy steel through precision stamping and heat treatment processes. It is used to connect the engine output gear to the rear wheel cone.
420h chain Features
Using solid seamless bushing process
Motomax the use of cold extruded seamless bushings instead of traditional rolled bushings, this structure eliminates the stress concentration at the joints, significantly reduces pin wear and extends the chain Service life.
Shot blasting strengthening treatment on the surface of chain plate
all 420H chain plates are treated by strict shot blasting process to improve the fatigue strength of parts by generating compressive stress on the surface, so as to ensure that the chain is not easy to break under long-term high-load operation.
Four-sided riveting and locking technology of pin shaft
We use high-precision four-sided riveting technology to fix the pin shaft. This reinforcement method greatly enhances the lateral stability of the chain, and can ensure the structure even under the extreme impact of frequent starting and braking. stable.
Forced pre-stretching treatment before leaving the factory
Each 420H chain will go through a factory-level professional pre-stretching process before packaging. By eliminating the initial elongation of the material in advance, the problem that wholesalers are most worried about the need for end customers to frequently adjust the chain is solved.
High standard heat treatment process control
relying on 30 years of manufacturing experience, we carry out deep quenching heat treatment on the pin shaft and roller, so that the surface hardness reaches the industrial standard, which greatly improves the wear resistance of the product while ensuring the core toughness.
Fully automated production line precision manufacturing
the Motomax production line realizes full automation from part assembly to performance testing, controls the processing tolerance within a very small range, ensures that the quality of each 1 chain is highly consistent, and perfectly adapts to major mainstream brands.

FAQ And Contact Us
Welcome to our Frequently Asked Questions page. We have compiled answers to common questions you may have, hoping to provide you with clear and quick solutions. If you cannot find the information you need here, please feel free to contact our customer support team.
Can the 420H chain be installed on a standard 420 tray?
Yes, the 420H is exactly the same as the pitch and inner width of a normal 420, but the chain plate is thicker, so it can provide a higher safety factor and longer life when used on a standard tray.
What international certifications does Motomaxsfr chain have?
Our factory has passed the IATF 16949 quality management system certification for the automotive industry, which means that our production processes and quality control have reached the level of international vehicle support.
Is this chain suitable for electric off-road vehicles?
Very suitable. The reinforced structure of the 420H is designed to cope with the instantaneous high torque generated by the electric motor, which can effectively prevent the chain from stretching or breaking during severe acceleration.
How to identify the authenticity of the Motomax 420H chain?
Each genuine Motomax chain has a clear brand logo and specifications stamping on the side plate, and the package is accompanied by a certificate of approval. Wholesalers can directly verify the batch through the official channels of our factory.
Have the factory chains been coated with lubricating grease?
Yes, all chains are soaked with special high-temperature grease in a vacuum environment before leaving the factory, and can be installed and used directly after unpacking. There is no need to apply additional oil at the initial stage to prevent dust accumulation.
Do you support OEM production?
We support the OEM and ODM customization needs of customers around the world, and can customize the color of the chain, surface treatment process and specific packaging specifications according to your requirements, and guarantee the brand’s trade secrets.
Please feel free to contact us. We look forward to hearing from you.
