Model HomeSpecsGalleryVideoApparelAccessoriesModel 2007
 Key Features:
  • YZ-bred advanced aluminum frame—carefully engineered from castings, forgings and extrusions enhances handling while retaining legendary Yamaha feel and characteristics.
  • Highly evolved high-revving five-titanium-valved engine starts with the push of a button.
  • Cool digital enduro computer offers speedometer, clock, tripmeter, etc., in basic mode or pace management functions such as timer, distance-compensating tripmeter, average speed, etc., when switched to race mode.
  • The WR250F is green sticker approved for California.
 New for 2008:
  • New 6Ah battery (up from 4Ah) for more cranking power.
  • A fluorination treatment of the plastic fuel tank reduces gas permeation — good for the environment and the EPA — and new, FKM breather and fuel hoses accomplish the same thing.
  • New-shaped lightweight brake pedal for enhanced performance and feel.
 Engine:
  • 249cc liquid-cooled, DOHC four-stroke with five titanium valves delivers excellent low- and midrange power, with high over-rev capacity and crisp, linear throttle response.
  • Special WR camshafts, carburetion and TPS tuning, exhaust and ignition systems work together to produce a quick-revving engine with great low and midrange power.
  • 37mm Keihin FCR flat-slide carburetor with throttle position sensor (TPS) ensures ultra-precise fuel/air mixing and lightning-quick throttle response.
  • Close-ratio five-speed gearbox tackles almost any terrain.
  • “No tools” airbox uses hinge-type quick-open lid. Battery rides low for excellent handling.
  • Digital CDI ignition system delivers more precise spark and monitors engine speed to ensure optimal timing for fast, strong response during hard acceleration.
  • Large-capacity radiators with reinforcements ensure maximum cooling efficiency with great strength.
  • Lightweight exhaust system maximizes engine power and allows hassle-free replacement of oil filter.
  • Aluminum muffler with USFS-approved spark arrestor looks trick and keeps things light.
  • Works-style clutch lever features oversize barrel adjuster for easy, on-the-fly adjustability of lever/cable play.
  • Electric start ensures easy restarts.
 Chassis/Suspension:
  • YZ-inspired aluminum frame reduces weight while optimizing mass centralization. An extensively tested assembly of aluminum forgings, castings and extrusions, the WR frame retains legendary Yamaha handling and response.
  • Removable aluminum rear subframe constructed of square-section tube for reduced weight.
  • Fully adjustable air-/oil-separate 48mm fork tubes deliver precise, fade-free handling; fork protectors provide excellent tube protection.
  • Tapered swingarm uses YZ-style linkage for controlled, compliant rear suspension action. Axle and holders reduce weight in a critical area.
  • The Kayaba shock provides 12.2 inches of travel with adjusters for high- and low-speed compression damping, rebound and spring preload and features a larger piggyback reservoir for excellent damping and fade resistance.
  • Wave disc brake rotors front and rear reduce unsprung weight and provide excellent performance. Front and rear calipers with aluminum pistons deliver strong stopping power with progressive feel.
  • Lightweight 21-inch front and 18-inch rear rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance.
  • Premium Dunlops offer unbeatable, competition-spec traction and excellent wear.
 Additional Features:
