428H chain provides ultra-high tensile strength and low torsional resistance with its thickened chain plate design. It is an ideal transmission choice for light electric motorcycles and leisure scooters. As a source production factory with a history of 33 years, the Motomaxsfr has passed the national specialized and special new certification, which can eliminate the cost of middlemen and provide you with highly competitive ex-factory price and stable mass supply guarantee.
428H chain is the 1 enhanced transmission chain made of high-quality alloy steel. The impact resistance is improved by thickening the chain plate. It is mainly used for the power transmission of 2-8KW power section vehicles.

428H chain adopts 2.0mm thick chain plate design, which improves the tensile strength by about 20% compared with the standard chain, effectively prevents the chain from stretching or breaking when starting under high load, and prolongs the service life.

The frictional resistance between chain links is reduced through the precision cold extrusion sleeve process, which can significantly reduce energy loss in 2-5KW motor applications, and help electric vehicles obtain longer single charge mileage.

the meshing accuracy between the roller and the sprocket is optimized, and the operating noise is stabilized at about 78 decibels with the Motomaxsfr patented buffer sprocket, thus solving the sensitive pain point of electric motorcycle users to abnormal transmission noise.

the pin shaft adopts special heat treatment process, the surface hardness is extremely high and the core is tough, and the elongation is extremely low under frequent switching of high torque, which greatly reduces the maintenance and adjustment frequency of end users.

This product has been strictly tested and can perfectly match all kinds of fuel and electric leisure scooters with speeds of 60 to 120 kilometers per hour, providing B2B customers with extremely high specification coverage and versatility.

With a 150000 square meter production base and more than 900 professional employees, it is Motomaxsfr to ensure that 428H chain can maintain highly consistent quality and on-time delivery even under large purchase orders.
