Vehicle Information
Yamaha WR250X Motorcycle - Dual-Sport (2008-2011)
The Yamaha WR250X, produced from 2008 to 2011, is a dynamic supermoto motorcycle known for its agile handling and street-oriented performance. It is powered by a robust 249cc liquid-cooled, DOHC, 4-valve, 4-stroke single-cylinder engine, delivering approximately 30 to 31 horsepower. This model was designed as a dedicated supermoto variant, featuring 17-inch wheels, street tires, and a firmer suspension setup compared to its dual-sport counterpart, the WR250R. Throughout its production run from 2008 to 2011, the WR250X maintained a consistent engine and was offered in a single trim level. There were no significant mid-cycle generation or engine changes during these years. Minor cosmetic updates included variations in color schemes, such as blue in 2008, black in 2009, and white for 2010-2011 models. It is important to note that some 2008 models were subject to a fuel pump recall, and all 2008-2011 WR250X models were affected by a recall concerning stator coil insulation issues. Q: How can I ensure parts fit my Yamaha WR250X?
