Motorcycle Transmission Chain

Our motorcycle chain are made of high-quality alloy steel, with small hardness tolerance after heat treatment to achieve higher toughness, tensile strength and impact resistance. The carbonitriding process for pin and bush increase the surface hardness for the components. Shot blasting process for the plates, bush and roller increase the fatigue resistance.

Our Super series chain used special pin, which used chrome alum coating and boronizing process increasing the surfance hardness from HV0.2 750 to HV0.2 2000, which is same with the abrasion standard from Japan, reducing the elongation from abrasion of the chain.

The normal motorcycle transmission with curled bush, designed for low perofrmance motorcycles with medium and low capacity up to 250CC and mopeds.


Chain Size:

420,  428, 428H,  520, 520H, 525, 525H, 530, 530H, 630.

Color Available: steel natural color, black finished, blue finished, yellow finished.


The Professional Chain with solid bush, designed for specific applications such as motocross, trial etc., suitable for almost all types of application up to 250CC.  

The Solid bush make the chain running more silent and long working life.

 a. Outstanding longer wear life. Conventional split bushings deform into a barrel shape when side plates are pressed on. Sold bushing has extremely cylindrical inside and outside bushing walls resulting in full contact to disperse bearing pressure. Less pressure ensures excellent wear resistance.
 b. up to 2-3 times longer wear life over curled bushing. The curled, split bushings have a seam where tiny space allows lubricant leakage resulting in shorter wear life. Solid bushing &has no seam resulting in lower bearing pressure allowing the bushing to retain lubrication resulting in much long wear life.
 c. Reliable perfomancer: solid bushing is cold-forged from steel rod, cold-forming process also works with the molecular structure(grain) of the steel running lengthwise in the bushing thereby increasing fatigue strength as well as preventing bushings from breakage,.


Chain Size:

 415P,  420P, 428P,  520P,  530P

Color Available: Golden finished, Silver finished
