Product Usage

 

• SELECTION & INSTALLATION

We strongly recommend lubricating the new connecting link before joining both ends of the new chain (refer to Fig. B). For the Clip type connecting link (FJ, RJ), ensure the open end of the clip is set opposite to the chain drive direction (see Fig. C). The FJ type connecting link features Press Fit Outer Plates that necessitate the use of the SFR Cutting & Riveting Tool for pressing on the side plates. For Rivet type connecting links (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 recommendations. The standard chain sag with the rider's load is 10 mm (see Fig. D).

 

• SELECTION & INSTALLATION

1. Always consult your distributor or local dealer, or refer to the SFR chain catalog or application chart to verify whether this chain and connecting link are suitable for your motorcycle. Improper selection and use can result in severe damage or injury.

2. Cut the old chain at its joint part. If your motorcycle has an endless chain or a chain with a Rivet type connecting link (ZJ), employ 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. Rotate the rear wheel to position the new chain (refer to Fig. A).
