Watch Document 72 Hours Season 8 Episode 30 Online

Riding a motorcycle might be hot in summer and cold in winter, but many riders would never consider any other mode of transport. Some even cut back on buying a daily coffee to save money for their bike. There is a large parts store in Tokyo where riders come to seek new accessories or simply to show off their prized vehicle. Among the steady stream of riders drawn to this store are a 75-year-old man who started a part-time job to buy a new bike, a hydroelectric power plant engineer whose career was inspired by a bike, and a man who liked bikes so much he became a courier on 2 wheels. For 3 days, we spoke to these people about why they can't get enough of their motorcycles.
