Calculate Preload Setting
WARNING
Do not exceed the motorcycle's Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR). Exceeding these weight ratings can lead to component failure and adversely affect stability, handling and performance, which could result in death or serious injury. (00016f)
Adjust suspension to suit load conditions, riding style and personal comfort. Increase preload to accommodate the total load. Reduce the preload if carrying less weight. Do not exceed maximum GVWR or GAWR when loading.
NOTE
To determine the motorcycle configuration check the model character stamped on the VIN. See Your Motorcycle → Vehicle Identification Number (VIN).
1. Add the weight of the rider to the total weight of the passenger and/or cargo to Identify the proper preload setting.
