Your passenger represents a considerable additional weight, which affects the handling of your bike. You will have to operate the throttle, clutch, and brakes more smoothly than when you are alone. You therefore need more time to slow down and stop and should always ride at a lower speed than usual. You need to check if your passenger understands how to keep the right position, use the footrests, place both hands, make signals, avoid touching hot motorcycle parts, etc.
Do not ride with a passenger unless he or she wears full protective gear. If you ride with a child, make sure he or she is mature enough to understand the responsibility, the child’s parents are informed, and it is legal to do so. The passenger should hold firmly to the operator’s waist, anticipate when the motorcycle accelerates or stops, and lean with the operator and bike in curves.
Your motorcycle should be designed with an extra seat and foot pegs or floorboards in order to carry a passenger. The extra weight requires you to adjust the tire pressure and, in some cases, the suspension. Check your owner’s manual for maximum weight and instructions.
