What is an important practice when adjusting mirrors for riding with a passenger?

When adjusting mirrors for riding with a passenger, having the passenger sit normally is crucial for achieving optimal visibility. This ensures that the mirrors are set in a way that provides the best possible view of the road behind you, taking into account the additional weight and positioning of the passenger.

When a passenger is seated properly on the motorcycle, it may cause slight shifts in the bike's balance and line of sight. By having them sit in their intended position while you adjust the mirrors, you can account for these changes and enhance your overall awareness of your surroundings. Proper mirror adjustment is key to ensuring safe riding, especially when sharing the bike with another person. Accurate positioning helps you spot vehicles or obstacles that may come up from behind, which is vital for maintaining safety during the ride.
