Product Usage

• SELECTION & INSTALLATION

For an optimal installation experience, we highly advise lubricating the new connecting link before joining both ends of the new chain (refer to Fig. B). For Clip-type connecting links (FJ, RJ), be sure that the clip's open end faces opposite the chain's drive direction (refer to Fig. C). The FJ-type connecting link comes with Press Fit Outer Plates, necessitating the use of the SFR Cutting & Riveting Tool for secure side plate installation. For Rivet-type connecting links (ZJ), employ the MOTOMAX KM500R Cutting & Riveting Tool to precisely fit the connecting link plates and accurately flare the pin head, following our comprehensive guidelines. To adjust chain sag, please refer to your motorcycle owner's manual. The standard chain sag, with rider load, should be 10 mm (see Fig. D).

• SELECTION & INSTALLATION

1. Ensure the compatibility of this chain and connecting link with your motorcycle by consulting your distributor, local dealer, or the SFR chain catalogue/application chart. An incorrect selection and use could lead to severe damage or injury.

2. Cut the old chain at its joint. For motorcycles equipped with an endless chain or a chain with Rivet-type connecting link (ZJ), use the SFR Cutting & Riveting Tool or a similar cutting tool for precision.

3. Secure the new chain to the end of the old one with a new connecting link. By rotating the rear wheel, the new chain will automatically be positioned correctly (refer to Fig. A).
