The 2007 MY TT-R90 is a great dirt machine for kids past the height of the 49cc entry-level bikes. Almost doubling the displacement of the smallest Yamaha dirt bike, the TT-R90 provides a non-intimidating feel, boosting the rider confidence while being a nifty platform for training and honing in the skills.
Air-cooled, 4-stroke, fun, and strong-pulling the 2007 MY TT-R90 comes with an easy-to-use semi-automatic 3-speed transmission which allows riders to focus on the track and care less about the secrets of the clutch work. built like a tank, this bike can take a lot of abuse and still work well in the backyard or on the track.
