Power Steering will provide multiple improvements to your machine. After installation, it is highly recommend to take time and learn your machines new handling characteristics and feel. 

Key Recommendations:

1. Power Steering Benefits will be noticed as soon as machine is moving.

2. Handlebar will have more noticeable deflection while at rest. As a result of speed sensitive operation, this is normal.

3. Check steering sensitivity at multiple speeds to best understand new handling characteristics and feel.

4. Without Throttle input, turning Handlebar back and forth unnecessarily is not recommended. This action is very hard on remaining stock steering components, Tie Rod Ends, and Power Steering unit. Like all SuperATV products, Power Steering kits were designed with riders in mind.
