Product Usage

 

• SELECTION & INSTALLATION

We strongly recommend lubricating a new connecting link before joining both ends of the new chain (Fig. B). For the clip-type connecting link (FJ, RJ), ensure the open end of the clip faces opposite the chain drive direction (Fig. C). The FJ type connecting link has Press Fit Outer Plates, requiring the SFR Cutting & Riveting Tool to press on the side plates. For the rivet-type connecting link (ZJ), use the MOTOMAX KM500R Cutting & Riveting Tool to press fit the connecting link plates and accurately rivet the pin head according to our recommended flare dimensions. For chain sag adjustment, adhere to the motorcycle owner's manual. The standard chain sag with the load of the riders should be 10 mm (Fig. D).

 

• SELECTION & INSTALLATION

1. Always consult your distributor, local dealer, or check the SFR chain catalogue or application chart to ensure this chain and connecting link are compatible with your motorcycle. Improper selection and use can lead to severe damage or injury.

2. Cut the old chain at its joint part. If your motorcycle came with an endless chain or a chain with a rivet-type connecting link (ZJ), use the SFR Cutting & Riveting Tool or a similar cutting tool.

3. Attach the new chain to the end of the old one using a new connecting link. By turning the rear wheel, the new chain will move into position (Fig. A).

 

• Motorcycle Chain Handing Instructions

The drive chain is a critical safety component for motorcycle operation. To ensure a safe ride, please carefully read and follow your motorcycle owner's manual and these instructions.
