Thank you for viewing. Tandem Touring Belt TB I was drawn to this product because it's the first in Japan designed to support children who fall asleep on motorcycles. It's well-made, so I believe it will allow for safe riding. I haven't used it much, so I think it's in very good condition, but please refrain from purchasing if you are sensitive to used items. I purchased it for around 15,000 yen. Thank you. The driver's physique should be between 150cm and 190cm in height, with a chest circumference of 140cm or less when wearing clothes. Also, the passenger's physique should be between 100cm and 150cm in height, weigh 40kg or less, and have a chest circumference of 110cm or less when wearing clothes. However, the height difference between the rider and passenger, minus the seat step of the motorcycle, must be between 0cm and 75cm.
