Troubleshooting Common Motorcycle Windshield Deflektor Problems

Motorcycle Windshield Deflektors are valuable accessories for motorcycles, offering enhanced wind protection, improved visibility, and increased comfort. However, like any accessory, they can sometimes present issues. This guide provides troubleshooting tips for common motorcycle windshield deflektor problems, ensuring you can maintain optimal performance and safety.

Wind Noise and Turbulence

Problem: Excessive Wind Noise

Cause: Incorrect height or angle of the Motorcycle Windshield Deflektor can cause air turbulence, leading to increased wind noise.


  1. Adjust the Height: Experiment with different heights to find the optimal position that reduces noise. The top edge of the extension should be just below or at the riderโ€™s eye level.
  2. Angle Adjustment: Tilt the extension slightly forward or backward to direct airflow over and around your head. Small adjustments can make a significant difference in reducing noise.

Problem: Turbulence Behind the Windshield

Cause: Poorly positioned Motorcycle Windshield Deflektor can create a low-pressure area behind the windshield, causing turbulence.


  1. Fine-Tune the Position: Adjust the height and angle to smooth out airflow. A higher position generally reduces turbulence.
  2. Use Wind Deflectors: Adding side deflectors can help manage airflow and reduce turbulence.

Vibration and Stability Issues

Problem: Motorcycle Windshield Deflektor Vibrates

Cause: Loose mounting hardware or incompatible extension can cause vibrations at high speeds.


  1. Tighten Mounting Hardware: Check all screws, bolts, and brackets to ensure they are securely tightened. Use thread locker if necessary to prevent them from loosening due to vibrations.
  2. Check Compatibility: Ensure the extension is designed for your motorcycle model. Universal extensions may require additional adjustments or stabilizing brackets.
  3. Add Damping Materials: Use rubber washers or grommets between the Motorcycle Windshield Deflektor and the mounting points to absorb vibrations.

Problem: Unstable at High Speeds

Cause: Improperly mounted or incompatible extension can affect stability, especially at higher speeds.


  1. Recheck Mounting: Ensure the extension is firmly attached and correctly aligned.
  2. Adjust the Angle: A more aerodynamic angle can help improve stability.
  3. Consider a Different Model: If stability issues persist, consider a different Motorcycle Windshield Deflektor designed for high-speed stability.

Visibility Issues

Problem: Glare

Cause: Transparent or untreated Motorcycle Windshield Deflektor can reflect sunlight or headlights, causing glare.


  1. Use Anti-Glare Coating: Apply an anti-glare film or coating to the extension.
  2. Consider Tinted Extensions: Tinted Motorcycle Windshield Deflektors can reduce glare without significantly affecting visibility.

Problem: Scratches and Cloudiness

Cause: Frequent exposure to debris, improper cleaning, or poor-quality materials can lead to scratches and cloudiness.


  1. Proper Cleaning: Use a microfiber cloth and mild soap to clean the extension. Avoid abrasive cleaners and cloths that can scratch the surface.
  2. Protective Coatings: Apply a protective coating specifically designed for acrylic or polycarbonate to reduce the risk of scratches.
  3. Polish Out Scratches: Use a plastic polish to remove minor scratches and restore clarity. For deeper scratches, professional polishing may be required.

Installation and Fitment Issues

Problem: Difficult Installation

Cause: Incompatible or poorly designed Motorcycle Windshield Deflektor can complicate the installation process.


  1. Follow Instructions Carefully: Ensure you are following the manufacturerโ€™s instructions step-by-step.
  2. Seek Professional Help: If installation is challenging, consider seeking help from a professional mechanic or someone experienced with motorcycle accessories.
  3. Check Compatibility: Make sure the extension is compatible with your motorcycle model and existing windshield.

Problem: Poor Fitment

Cause: Universal extensions may not fit perfectly on all motorcycle models.


  1. Adjust Mounting Points: Modify the mounting points or use adjustable brackets to achieve a better fit.
  2. Custom Extensions: Consider investing in a model-specific Motorcycle Windshield Deflektor for a precise fit.

Maintenance Issues

Problem: Frequent Loosening of Mounting Hardware

Cause: Vibrations and regular use can cause mounting hardware to loosen over time.


  1. Regular Checks: Periodically check and tighten all mounting hardware.
  2. Use Thread Locker: Apply thread locker to screws and bolts to prevent them from loosening.
  3. Upgrade Hardware: Use higher-quality or vibration-resistant mounting hardware if problems persist.

Problem: Material Degradation

Cause: Prolonged exposure to UV rays, weather elements, or improper maintenance can degrade the Motorcycle Windshield Deflektor material.


  1. UV Protection: Apply a UV protectant regularly to prevent sun damage.
  2. Proper Storage: Store your motorcycle in a shaded or covered area when not in use. Use a cover to protect the Motorcycle Windshield Deflektor from the elements.
  3. Regular Cleaning: Clean the extension regularly with appropriate products to maintain its condition.


Addressing common Motorcycle Windshield Deflektor problems involves understanding the causes and implementing appropriate solutions. By adjusting the height and angle, ensuring proper installation, and maintaining the extension correctly, you can enjoy enhanced wind protection, improved visibility, and a more comfortable riding experience. Regular maintenance and checks will help keep your Motorcycle Windshield Deflektor in optimal condition, ensuring a safe and enjoyable ride.
