Motorcycle Chain Handing Instructions

Drive chain is a critical safety part for motorcycle driving. To ensure safe drive, you are kindly requested to peruse and observe your motorcycle owner's manual and the following instructions.

SELECTION & INSTALLATION

1.Be sure to consult your distributor / local dealer or check with SFR chain catalogue or application chart whether this chain and connecting link are applicable for your motorcycle. Improper selection and use may cause serious damage or injury. 2.Cut the old chain at its joint part. If your motorcycle came with an endless chain or a chain with Rivet type connecting link(ZJ), use SFR Cutting & Riveting Tool or similar cutting tool. 3.Fit the new chain to the end of the old one, using a new connecting link. By turning the rear wheel, the new chain will come in position(Fig. A) 

SELECTION & INSTALLATION

We strongly recommends you to lubricate a new connecting link before connecting both ends of the new chain(Fig. B) Clip type connecting link (FJ,RJ) The open end of the clip must be set opposite the chain drive direction(Fig. C). FJ type connecting link has Press Fit Outer Plates that require SFR Cutting &Riveting Tool to press on the side plates.
