Product Usage

• SELECTION & INSTALLATION

We strongly recommend applying lubrication to the new connecting link before coupling both ends of the new chain, as shown in Fig. B. For Clip-type connecting links (FJ, RJ), make sure the clip's open end points away from the chain's driving direction, as illustrated in Fig. C. The FJ-type connecting link comes equipped with Press Fit Outer Plates, requiring the use of the SFR Cutting & Riveting Tool to secure the side plates. For Rivet-type connecting links (ZJ), utilize the MOTOMAX KM500R Cutting & Riveting Tool to expertly press fit the connecting link plates and precisely flare the pin head in accordance with our detailed instructions. When adjusting the chain sag, refer to the motorcycle owner's manual. The optimal chain sag with the rider's weight should measure 10 mm, as shown in Fig. D.

• SELECTION & INSTALLATION

1. It is crucial to verify that this chain and connecting link are compatible with your motorcycle. Consult your distributor, local dealer, or reference the SFR chain catalogue/application chart to ensure correct selection. Improper selection and usage may result in severe damage or injury.

2. To remove the old chain, cut it at its joint. If your motorcycle is equipped with an endless chain or a chain with a Rivet-type connecting link (ZJ), employ the SFR Cutting & Riveting Tool or an equivalent cutting tool.

3. Secure the new chain to the end of the old chain by using a new connecting link. Rotate the rear wheel to properly position the new chain, as illustrated in Fig. A.
