Yamaha Unveils All-New SuperMoto Road Machine
This supermoto-inspired bike is built for riders who spend more time on paved surfaces, not that the occasional dirt road is going to slow anybody down much. This bike is directly descended from the YZ and WR off-road machines. Not enthusiasts have both… off-rod prowess and street accessibility.
ALL-NEW FOR 2008 - This motorbike is directly descended from our YZ motocrossers and WR off-road machines. The all-new WR250X is here to make Yamaha’s off-road prowess street accessible.
The 08 Yamaha Supermoto WR250X FI is not exactly an enduro, a supermoto or a sportbike motorcycle. 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.
Fuel Injection
The engine is a fresh-sheet design 250cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability. This is Yamaha’s 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.
Optimum combustion combined with a maximum power at 10,000 rpm provides the rider with an excellent power across the rev band. The ECU-controlled EXUP exhaust valve, along with an electronic intake control valve, broadens the powerband.
