4. Safety Information
Always prioritize safety during installation and maintenance. If you are unsure about any step, consult a qualified motorcycle mechanic. Ensure the motorcycle is stable and cool before beginning work. Wear appropriate personal protective equipment, such as gloves and eye protection.
5. Setup and Installation
The Evotech Performance Radiator Guard is designed for straightforward installation using the motorcycle's existing mounting points. No permanent modifications to the motorcycle are required.
- Preparation: Park the motorcycle on a level surface and ensure it is stable. Allow the engine and radiator to cool completely.
- Access: Depending on your motorcycle model, it may be necessary to remove certain fairings or components to gain clear access to the radiator. Refer to your motorcycle's service manual for specific instructions on component removal.
- Positioning: Carefully position the Evotech Performance Radiator Guard in front of the motorcycle's radiator. Ensure the guard aligns with the existing mounting points.
- Secure Fasteners: Use the provided fitting hardware to secure the radiator guard to the motorcycle. Hand-tighten all fasteners initially to ensure proper alignment.
- Final Tightening: Once aligned, progressively tighten all fasteners to the manufacturer's recommended torque specifications. Avoid over-tightening.
- Check Clearance: Verify that the installed radiator guard does not interfere with any other motorcycle components, such as the front wheel, suspension, or hoses, during full steering lock and suspension travel.
- Reassembly: Reinstall any fairings or components that were removed during step 2.

6. Operating Instructions
The Evotech Performance Radiator Guard operates passively by providing a physical barrier against road debris. Once correctly installed, it continuously protects the radiator's delicate cooling fins from impacts by stones, insects, and other foreign objects, thereby preventing potential damage and maintaining the radiator's efficiency. No user interaction is required for its operation.
7. Maintenance
Regular maintenance ensures the longevity and effectiveness of your radiator guard:
- Cleaning: Periodically clean the radiator guard to remove accumulated dirt, dust, and debris. Use a soft brush or low-pressure water spray. Avoid high-pressure washers directly on the radiator fins.
- Inspection: Regularly inspect the guard for any signs of damage, such as bends, cracks, or loose fasteners. Check the anti-vibration pads for wear.
- Fastener Check: Ensure all mounting fasteners remain securely tightened. Re-tighten if necessary, adhering to recommended torque specifications.
8. Troubleshooting
If you encounter issues with your radiator guard:
- Loose Fitment: If the guard feels loose, check all mounting fasteners and ensure they are tightened correctly. Verify that anti-vibration pads are properly seated.
- Vibration/Noise: Ensure all fasteners are tight and that the anti-vibration pads are in place. Check for any contact points between the guard and other motorcycle components.
- Damage: In case of significant impact or damage to the guard, inspect the underlying radiator for any corresponding damage. A severely damaged guard should be replaced to ensure continued protection.
