The 420 electric motorcycle chain is designed with high strength and impact resistance, specially designed for enlightenment off-road and light sports vehicles, ensuring solid and durable power transmission and smooth operation. As a national-level “specialized, special and new” high-tech enterprise with a history of 33 years, Zhengzheng Technology (Motomaxsfr) is deeply engaged in source manufacturing, eliminating the middleman link, and providing global wholesalers with more competitive ex-factory prices and efficient Delivery guarantee.
The 420 electric friction chain is a key transmission component connecting the driving sprocket and the driven sprocket. It is made of high-strength steel and converts the motor torque into wheel propulsion through the mutual meshing between the chain links.
Motomaxsfr high-frequency quenching of the pin and roller of the 420 chain, the surface hardness reaches the industry-leading standard, effectively reducing chain link elongation, and increasing the service life by more than 30%.
In view of the frequent acceleration and braking in off-road riding, the chain strengthens the thickness and toughness of the chain plate, and can withstand the impact of instantaneous high load without deformation, ensuring the reliability of the competitive environment.
With the use of special buffer sprocket, the chain and tooth profile can achieve high-precision meshing, and the operating noise is controlled below 76 decibels, which significantly improves the riding comfort of the driver.
the use of high-precision transmission system design, reduce the chain link in high-speed operation of the energy loss, so that 2 to 5 kW of the electric motor can be more efficient output power.
The product has passed strict tensile strength tests to ensure long-term stable operation at 60 kilometers per hour to meet the high-frequency and high-intensity use requirements of light sports vehicles for transmission systems.
The surface has been specially processed to have excellent anti-rust performance, even in muddy or wet off-road conditions, it can still maintain structural integrity and reduce maintenance costs.
| Specifications and Models | Applicable vehicle types | Motor power range | Maximum design speed | Operating noise decibels | Performance positioning |
| Standard 420 | Enlightenment of off-road and light sports vehicles | 2-5KW | 60KM | 76 decibels | Economical, practical, and cost-effective |
| 420 Pro | Off-road racing, light sports bikes | 3-8KW | 60KM | 75 decibels | Lightweight and more impact resistant |
| 420 SO | Off-road racing, light sports bikes | 3-6KW | 70KM | 79 decibels | Low power consumption, with sealing ring design |
are suitable for distributors looking for high-quality, cost-effective transmission parts to help them establish a stable supply chain advantage in the entry-level off-road electric motorcycle market.
provides high-strength 420 specification chains for competitive teams seeking ultimate durability and lightweight, meeting the stringent requirements of high-frequency competition and training.
provides standardized drive system solutions that meet the IATF 16949 system certification for manufacturers producing models in the 1 to 8 kW power range.
provide standard and reliable accessories for stores that replace and upgrade electric motorcycle chains on a daily basis to ensure the riding safety and after-sales reputation of end users.
The core material of the chain is high grade 20CrMnTi alloy steel. The pin shaft is treated with carbon-nitrogen co-penetration to form a very high hardness surface, and the chain plate is made of medium-carbon alloy steel and is strengthened by shot peening, which significantly improves its anti-fatigue strength. All raw materials comply with national standards to ensure stable performance under various harsh conditions.
We provide professional technical consultation to match the best transmission scheme according to your motor parameters. After-sales includes a 12-month quality warranty, providing fast claim channels and 24-hour technical support response for bulk purchase customers.
Under normal maintenance, the expected mileage of the Motomaxsfr 420 chain can reach 15000 to 20000 kilometers. It is recommended to check the chain tightness regularly and apply chain oil. It is forbidden to use strong acid and alkali solvent for cleaning.
