Red Bluff Yamaha
The YAMAHA WR250R Dual Sport - 2009
When the road ends, it's just getting started
The WR250R draws upon over 50 years of Yamaha experience, on pavement and off, to bring
you a bike that'll take you practically anywhere - one hundred percent legally. More power
than you might expect flows from it high-tech, fuel-injected DOHC engine while a hybrid
aluminum frame keeps you in compete comman. Pavement optional. Rated at 71 MPG
Estimated Fuel.
FEATURES
- Directly descended from our YZ motocrossers and WR off-road
machineseven the original Yamaha YA-1 of 1955the WR250R is here to make
Yamahas 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.
- The WR250R achieves fuel economy up to an estimated 71 mpg** with a
fuel tank that holds 2 gallons of gas.
|
- 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.
- Large titanium intake valves with WPC processed high lift cams, a
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 pluganother 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 keeps the mass concentration up and
the bike quiet.
- Electric start only: Leaving off the kickstarter keeps it light and
simple.
|
- YZ / WR250-inspired semi-double-cradle frame uses a main frame of
cast and forged aluminum sections, with high-strength steel downtubes for excellent
strength and rigidity characteristics.
- Asymmetrical swingarm provides excellent strength/rigidity balance
and a dynamic look. Cast aluminum crossmembers, extruded arms and a 22mm rear axle are
carefully tuned for optimum handling.
- Fully adjustable 46mm fork provides 10.6 inches of wheel travel. A
forged lower triple clamp and a cast upper one help give outstanding front-end feel. An
aluminum steering stem reduces weight.
- Linkage-mounted rear shock provides 10.6 inches of travel with
adjusters for compression damping, rebound damping and spring preloadand features a
14mm rod and 46mm cylinder for excellent damping and fade resistance.
- Wave brake rotors front and rear reduce unsprung weight and provide
excellent performance. Rear pedal is forged aluminum.
|
- A slim, steel fuel tank is shaped with knee grip in mind, and the
entire ergonomic layout is designed to make the rider feel like part of the bike.
- Narrow, YZ-inspired seat features gripper-type cover for great
seat-of-the-pants feel. Seat height is 36.6 inches.
- WR enduro-style instrument panel provides excellent visibility in
spite of the compact size. Basic mode provides speed, clock, tripmeter and self-diagnostic
function. Measurement mode includes stopwatch, distance-compensating tripmeter, etc.
- Minimalist front and rear fenders are designed for function,
simplicity and lightness.
- Bodywork with separate radiator heat outlet helps keep engine and
rider cool.
- Lightweight headlight and LED taillight maximize visibility and draw
less current.
- Adjustable front brake lever.
