2010 Yamaha Wr250r Dual sport Motorcycle in Albemarle, NC

SELLER DESCRIPTION

2010 YAMAHA WR250R , Directly descended from our YZ motocrossers and WR off-road machines even the original Yamaha YA-1 of 1955 the WR250R is here to make Yamaha s off-road prowess street accessible. Not exactly an enduro model and not a streetbike either, the WR250R is for riders who ride off-road more than on. Its sibling, the supermoto-inspired WR250X, is for riders who spend more time on pavement. Engine: 250cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability. Pentroof combustion chamber with downdraft-type straight intake helps make excellent power across the rev band, with maximum power at 10,000 rpm. 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. An ECU-controlled EXUP exhaust valve, along with an electronic intake control valve, broadens the powerband. High lift cams have WPC surface treatment in which the surface is sprayed with fine powder at over 100 meters per second to increase surface hardness. Three-axis engine layout keeps the engine compact. Wet sump tucks between frame rails to keep the engine height down. Rare earth-type ACM alternator keeps the weight down while providing all the current needed to run the FI and lighting systems. Direct ignition coil sits atop the spark plug another first on a Yamaha on/off-road model. Six-speed gearbox provides a wide spread of ratios, with shower-type lubrication for reliability. A special light-action clutch makes shifting a snap. Tucked-in, three-chamber muffler helps keep mass centralized and the bike quiet. Electric start only: Leaving off the kickstarter keeps it light and simple.
