The Yamaha homepage features information on the new WR250X for 2009
According Yamaha, the WR250X is not exactly an enduro, a supermoto or a sportbike, the WR250X is for riders who ride mostly paved surfaces. Its sibling, the off-road inspired WR250R, is for riders who spend more time in the dirt.
Directly descended from YZ motocrossers and WR off-road machines—even the original Yamaha YA-1 of 1955— Yamaha says the WR250X is here to make Yamaha’s off-road prowess street accessible.
The WR250X also features the first use of fuel injection on a 250 Yamaha on/off-road bike. The system relies on input from a crank sensor, intake air pressure sensor and throttle position sensor feeding a compact ECU to provide optimum combustion.
