About the Product

Important Note: Motorcycle chains are a crucial part of your drivechain system, installation should always be done by a qualified mechanic to prevent damage / failure of the chain.

Precision Forging Process

• We make our ThreeD chains highly Stiff, leading to better acceleration and efficient engine work

Original Special Plate with Thghtening Hole

• We create a lighting hole in each inner plate without weakening the plate according to the computer analysus. The plate enables the chain to be light, remove muf from the hole and dissipate heat effectively. 

Improvemebt of Transmission Efficiency

• Our ThreeD parts are precisely manufactured, leading to a great improvement of transmission efficiency. 

Adoption of Special Pin

• We create a hole on both ends of the pin to make the chain lighter. 

Edge-Cut Inner Plate

• Reduces friction and realizes smooth engagement with the sprockets.

EK Chain Installation - Guide to Master Links

When you purchase a brand new motorcycle chain, the length of chain contains 1 single "master link" and 100+ standard links. After you cut the chain to the proper length with a chain cutting too and loop it around your sprockets, the master link is used to connect one end of the chain to the other. There are a number of master link styles available that require different tools for install, some you can clip with a simple wrench and others that require a specific tool.
	Rivet-Type Master Link (MLJ) (requires a Rivet Tool) A Rivet-style master link is arguably the strongest possible master link style and is designed much like the other standard links on the chain. It requires a special chain riveting tool to crimp the master link and is a permanent fastener. You will need to cut the chain with a special chain cutting tool for uninstallation.
	Semi-Press Fit Clip-Type Master Link (SKJ) (only requires pliers) The Semi-Press fit Clip-type master link is designed to "clip" onto the standard link with only a set of pliers needed. This semi-press fit design requires a little more pressure than the Slip Fit design but offers a tighter fit and better dependability.
	Screw Type Master Link (SLJ) (only requires wrench & pilers) The Screw type master link is available as an option for some sealed chains and was developed for racers who needed a quick and secure way of installing chains without needing a chain riveting tool. This screw type master link uses screws to secure the connection between the master and standard links and only require a wrench & pilers for installation.
