15: Justin Timberlake
Being part of the mega pop group N-Sync was fruitful for Justin Timberlake. He has long been known for showing off his custom car collection, but he also has a few custom motorcycles. His long black chopper was built by Jesse James of West Coast Choppers. There was a time when almost every singer and sports star had a bike built by James (via Go Rollick).

Timberlake isn’t one of the celebrities who try to pull off a biker image, but he enjoys riding his bike on the open road. Living in the hills of Los Angeles means there are many open roads where he can take this thing out in the open. Timberlake prefers the long and smooth ride of a chopper rather than a sports bike.
