The 2011 MY YZ85 is the smallest member in Yamaha's racing bike family, a 2-stroke machine that's great for teaching kinds what competition really is. This means a manual 6-speed transmission, adjustable suspensions, a bulletproof liquid-cooled engine and a tough-as-nails steel frame which can take a lot of beating.
Add in a bevy of other racing-grade components and technologies and you'll see why the YZ85 is not exactly your common beginner bike.
