2005 Yamaha Banshee

🏁 2005 Yamaha Banshee 350 Overview

The 2005 Banshee represents the last of a dying breed—a two-stroke, twin-cylinder sport ATV in a world that was quickly being taken over by four-stroke machines. By this time, Yamaha had already released the four-stroke YFZ450, but the Banshee stayed on as the wild, high-revving, no-holds-barred option for die-hard thrill seekers.
