A new 2014 Yamaha 3-Wheel motorcycle, commonly known as a trike, costs around $26,000 as of 2015. As with other motorized vehicles, however, you can find older and used models within various price ranges.
As an alternative to buying a trike, a company named Voyager sells conversion kits that allow the installer to convert larger motorcycles into a three-wheeled trike. The conversion kit costs between $7,000 to $8,000, and an average installation costs around $1,500. Used Yamaha trikes from the late 1990s through the early 2000s can range from $6,000 to $20,000 depending on the mileage and the modifications installed on the trike.
