Product Usage

• SELECTION & INSTALLATION

For optimal performance, we strongly recommend lubricating the new connecting link before attaching both ends of the new chain (see Fig. B). For Clip-type connecting links (FJ, RJ), ensure the clip's open end faces opposite the chain's drive direction (see Fig. C). The FJ-type connecting link includes Press Fit Outer Plates, requiring the SFR Cutting & Riveting Tool for precise side plate application. For Rivet-type connecting links (ZJ), utilize the MOTOMAX KM500R Cutting & Riveting Tool to accurately press fit the connecting link plates and correctly flare the pin head as per our guidelines. To adjust chain sag, refer to your motorcycle owner's manual. Standard chain sag with rider load should be 10 mm (see Fig. D).

• SELECTION & INSTALLATION

1. Ensure compatibility of this chain and connecting link with your motorcycle by consulting your distributor, local dealer, or the SFR chain catalogue/application chart. Incorrect selection and usage can result in severe damage or injury.

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

3. Attach the new chain to the end of the old one using a new connecting link. By rotating the rear wheel, the new chain will be expertly positioned (see Fig. A).

• Motorcycle Chain Handling Instructions

The drive chain is a crucial safety component in motorcycle operation. For a secure ride, please closely review and adhere to your motorcycle owner's manual as well as the following guidelines.
