2008 Yamaha Dual Sport bikes.

 

Yamaha is please to announce the all new XT250. This is not just a reworked XT225, but instead a brand new machine with more power, better brakes and a completely new look.

We’re not just stopping there, we’re also introducing the all new WR250R and WR250X. The WR250R is a dual purpose machine that blends a mixture of love for both the street and the dirt. The WR250X with it’s 17′ wheels is nothing short of SuperMoto inspired. Both bikes feature an all new DOHC four valve 250cc four-stroke engine, with a six speed transmission and FUEL INJECTION, a first for this class.

Most importantly all three models are completely street legal and very dirt capable.

ALL-NEW WR250R FOR 2008:

ENGINE:
 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.

 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 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 keeps the mass concentration up and the bike quiet.

 Electric start only: Leaving off the kickstarter keeps it light and simple.

CHASSIS/SUSPENSION:
 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 preload-and 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.

ADDITIONAL FEATURES:
 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.

 Large titanium intake valves have WPC coating, a 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.

 Electric start only: Leaving off the kickstarter keeps it light and simple.

CHASSIS/SUSPENSION:
 17-inch wheels mount radial street rubber in 110 front and140mm rear widths and help lower the seat approximately 1.4 inch compared to the WR250R.

 One-tooth smaller rear sprocket (13/42) works with the smaller-diameter tires to bring out the WR250X’s strong accelerating character.

 Stiffer springs front and rear and street-oriented damping settings reduce pitch compared to the WR250R for excellent pavement performance.

 YZ/WR250-inspired semi-double-cradle frame uses a main frame of cast and forged aluminum sections, with high-strength steel downtube 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 10.4 inches of travel with adjusters for compression damping, rebound damping and spring preload-and features a 14mm rod and 46mm cylinder for excellent damping and fade resistance.

 Wave brake rotors front and rear, including a large, 298mm front disc, reduce unsprung weight and provide excellent performance. Rear pedal is forged aluminum.

XT250

ENGINE:
 New 249cc air-cooled four-stroke with 9.5:1 compression makes maximum power at 7500 rpm and maximum torque at 6500 rpm for great on- and off-road performance.

 A light-and-strong forged piston inside a plated cylinder helps dissipate heat more efficiently, increasing both performance and durability. New 33mm vacuum-type carburetor keeps the airflow up for excellent performance and throttle response.

 A lightened crankshaft helps provide quick responsive power. Wide-ratio five-speed transmission for maximum power and performance in a wide range of terrain and conditions. Hassle-free pushbutton electric starting adds extra convenience and reliability.

 A new front fork with 8.9 inches of travel and revised damping soaks up the rough stuff, both on-road and off. A new aluminum lower triple clamp keeps the weight down.

 Maximum turning angle of the handlebar is 51 degrees-almost like a trials machine. Combined with a short wheelbase of only 53.5 inches, the XT250 has a super-tight turning radius for excellent maneuverability.

 A new rear shock provides 7.1 inches of wheel travel through a progressive, Monocross-style linkage system for a smooth ride.

 21-inch front and 18-inch rear aluminum wheels are extremely durable and reduce unsprung weight for enhanced suspension performance and handling. New 245mm front disc and 203mm rear disc brakes combine to deliver superb stopping power on both paved and unpaved surfaces.

 11.2 inches of ground clearance means you’ve got serious off-road capability, and a heavy-duty aluminum skid plate adds protection.ADDITIONAL
