What Should You Check Before Shipping Your Bike Off to the Dealer?

Does your Road King suffer from wobbling or wiggling? The first thing to check is the Road King tire pressure. But if that’s already within the recommended range, it’s time for further inspection. Here are some other potential solutions before you send your bike off to a dealer:

  • Check the wheel bearings: Check your wheel bearings for looseness or wear and tear. Listen carefully when you spin the wheels if you can hear any grinding or rumbling noises; these are signs that something is awry. Wobbling and vibration could be symptoms of a bigger issue with your wheel bearings, so it’s important to pay attention to how they’re performing.
  • Check the brakes: When your brake pads are in disrepair or your rotors have become warped, you may feel a quivering sensation upon braking.
  • Check the steering: Unstable handling on a motorcycle can be caused by loose or worn-out components in the steering system, such as neck bearings, handlebar clamps and fork legs.
  • Check the tires: If your tires are worn-out, outdated, or have inconsistent wear patterns, they can lead to instability. To maintain a safe driving condition and control of the vehicle, it is important to ensure that you always keep up with tire replacement and verify the tread depth.


Ensuring optimal Road King tire pressure is pivotal for the reliability and performance of your Harley Davidson Road King motorcycle. By regularly inspecting the tire pressure, you can help prevent unsteadiness, instability, and other potential problems.

Whenever you’re riding, make sure to double-check the recommended Road King tire pressure for your bike model. Adjust it based on your weight, what you are transporting and the terrain; if issues or wobbling persist after checking that first step then inspect all other components before sending in your bike for repair.
