2011 YAMAHA TT-R230A, YZ-inspired handling and looks, and a stout 223cc air-cooled, SOHC four-stroke producing predictable, broadband power, make the TT-R230 a great choice for beginner and intermediate riders. Competition-style flat seat/tank junction for great rider mobility. Electric start makes getting started a complete pushbutton exercise. A low seat height on top of a long-travel suspension and 11.6 inches of ground clearance make this a serious trailbike that s also accessible to a wide range of riders. Steel, diamond-type-design frame means great handling and strength.
