5. Operating and Functionality
Once installed, the Evotech Performance Rear Spindle Sliders function passively. Their primary purpose is to protect the rear axle, swingarm, and other related components during a slide or impact. The innovative design allows the nylon bobbin head to rotate on impact, which helps to dissipate energy and reduce the likelihood of the slider "digging in" to the ground, thereby minimizing damage to the motorcycle.
6. Maintenance
To ensure the longevity and effectiveness of your Evotech Performance Rear Spindle Sliders, regular maintenance is recommended:
- Inspection: Periodically check the bobbins, spacers, and spindle for any signs of wear, cracks, or damage. Replace any damaged components immediately.
- Cleanliness: Keep the sliders clean from dirt and road grime. Use a mild soap and water solution for cleaning.
- Fastener Check: Regularly verify that the nuts and washers securing the sliders are tight and have not loosened due to vibration.
- Post-Impact: After any incident involving contact with the sliders, thoroughly inspect them and the surrounding motorcycle components for damage. It is highly recommended to replace sliders after an impact to ensure continued protection.
7. Troubleshooting
This product is relatively simple, and most issues are related to installation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Slider feels loose after installation. | Fasteners not tightened sufficiently. | Ensure nuts and washers are tightened to the motorcycle manufacturer's specified torque. |
