If the rear suspension of your Honda CB Hornet 160cc motorbike is releasing slowly after compression, there could be a few possible causes:
Worn or Damaged Suspension Components: Over time, the suspension components, such as the shock absorber or the spring, can wear out or become damaged. This can lead to a loss of damping ability or reduced rebound speed, resulting in slow release of the suspension after compression.
Insufficient Suspension Fluid: If there is a low level of suspension fluid or if the fluid is degraded, it can affect the performance of the rear suspension. Insufficient fluid can result in inadequate damping, causing the suspension to release slowly after compression.
Incorrect Suspension Adjustment: Improper adjustment of the suspension settings, such as preload or rebound damping, can affect the suspension's behavior. If the settings are not correctly adjusted for your weight or riding conditions, it can result in slow rebound after compression.
Contaminated or Sticky Suspension Components: If the suspension components, particularly the shock absorber, have become contaminated or are sticking due to dirt, grime, or other foreign substances, it can impact their performance. This can result in slow release of the suspension after compression.
To address the issue, you can consider the following steps:
Inspect the Suspension Components: Check the condition of the suspension components, including the shock absorber and spring, for any signs of wear, damage, or leaks. Replace any worn or damaged parts as necessary.
Check Suspension Fluid Level and Quality: Verify the suspension fluid level and condition. If the fluid level is low or if it appears degraded or contaminated, consider draining and replacing the suspension fluid following the manufacturer's specifications.
Adjust Suspension Settings: Ensure that the suspension settings, such as preload and rebound damping, are correctly adjusted for your weight and riding preferences. Consult the owner's manual or seek guidance from a qualified technician to properly adjust the suspension settings.
Clean and Lubricate Suspension Components: If there is any contamination or stickiness on the suspension components, clean them thoroughly and apply appropriate lubrication or grease as recommended by the manufacturer.
If the issue persists or if you are uncertain about performing the necessary checks and adjustments, it's recommended to consult a professional technician or take your motorcycle to an authorized Honda service center for a comprehensive inspection and proper diagnosis of the rear suspension issue.
