Product Usage

• Selection & Installation

We strongly advise lubricating a new connecting link before securely connecting both ends of the new chain (as shown in Fig. B). For clip-type connecting links (FJ, RJ), ensure the clip's open end is opposite the chain drive direction (Fig. C). The FJ type link requires the SFR Cutting & Riveting Tool for pressing the side plates. For rivet-type links (ZJ), use the MOTOMAX KM500R Tool to press-fit and precisely rivet the pin head with recommended flare dimensions. For chain sag adjustment, refer to your motorcycle owner's manual. A standard chain sag with rider load is 10 mm (Fig. D).

• Selection & Installation

1. Always consult your distributor, local dealer, or check the SFR chain catalogue or application chart to confirm compatibility with your motorcycle. Incorrect selection or use may lead to severe damage or injury.

2. Remove the old chain at its joint. For motorcycles equipped with an endless chain or rivet-type link (ZJ), utilize the SFR Cutting & Riveting Tool or a similar device.

3. Attach the new chain to the old one's end using a new connecting link. Rotate the rear wheel to position the new chain correctly (as illustrated in Fig. A).

 

• Motorcycle Chain Handling Instructions

The drive chain is an essential safety component for motorcycle operation. To ensure safe riding, we urge you to adhere to your motorcycle owner's manual and follow these important guidelines.
