4. Setup and Installation
Follow these steps carefully for proper installation of the rear fender:
- Preparation: Park the motorcycle on a flat, stable surface. Ensure the engine is off and cool. If necessary, lift the rear wheel using a suitable stand to provide better access.
- Remove Old Fender (if applicable): Locate the mounting bolts or clips securing the existing rear fender. Carefully remove them using appropriate tools. Keep track of all hardware.
- Clean Mounting Area: Thoroughly clean the area where the new fender will be mounted to remove any dirt, grease, or debris. This ensures a secure fit.
- Position New Fender: Align the ACERBIS Rear Fender with the mounting points on your motorcycle's subframe or swingarm. Ensure all holes line up correctly.
- Secure Fender: Insert the provided or original mounting bolts through the fender and into the corresponding holes on the motorcycle. Hand-tighten all bolts first.
- Final Tightening: Once all bolts are in place, progressively tighten them using a torque wrench to the manufacturer's specified torque settings for your motorcycle model. Do not overtighten, as this can damage the plastic fender or mounting points.
- Inspect: After tightening, gently check the fender for any looseness or improper alignment. Ensure it is securely attached and does not interfere with any moving parts (e.g., wheel, chain).
5. Operating Considerations
The ACERBIS Rear Fender is a static component designed to protect the rider and motorcycle from debris and water kicked up by the rear wheel. No specific operational steps are required after installation. However, regular inspection is recommended to ensure its continued effectiveness.
