Unique Features
� Electric-start system for easy starting in all conditions.
� Gas-tank capacity is 1.9 gallons.
� Resettable, easy-to-read three-digit odometer.
� USDA-qualified muffler/spark arrester.
� Powerful 35-watt halogen headlight features an innovative lens for a wide range of illumination.
� Integrated LED taillight in rear fender.
� Convenient sidestand.
� Easy-access air filter.
� Wide-ratio five-speed transmission.
� Suspension tuned for competitive off-road riding needs.
� 18-inch rear wheel for greater flat-tire protection.
Engine/Drivetrain
� Powerful four-stroke 249cc liquid-cooled four-valve Unicam� engine is designed to produce power across a wide rpm band for easy-to-control operation (see Technology Section).
� Electric starter drives the clutch side of the crankshaft to provide superior lubrication to starter gears and produce a narrow engine with a short, strong crankshaft.
� Compact, lightweight engine assembly weighs only 59.3 pounds.
� ACG cover, clutch cover and cylinder-head cover are made of magnesium to reduce engine weight.
� Forged 12.9:1-compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
� 37mm Keihin FCR-type carburetor features four rollers on the flat slide, resulting in light throttle effort, smooth operation, crisp throttle response and excellent rideability.
� Carburetor features a Throttle Position Sensor (TPS) to help maintain linear throttle response throughout the rpm range.
� Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.
� Exhaust system uses a lightweight stainless-steel exhaust header and muffler equipped with spark arrester.
� Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator design, and coolant recovery tank.
� Gear-driven balancer reduces vibration and drives the water pump. Eight clutch plates provide the surface area necessary to handle the engine's massive torque, while carefully matched clutch springs provide a light feel at the lever.
� T-ring- sealed chain is approximately 1.6mm narrower and is stronger compared to conventional chains.
� Durable five-speed wide-ratio transmission.
SUSPENSION
� Fourth-generation Twin-Spar Aluminum Frame with forged-aluminum steering head (see Technology Section).
� 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight-aluminum spoke nipples as used on the CRF250R.
� Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity.
� Rear-axle diameter of 25mm and large-diameter bearings provide optimum rigidity to withstand torturous off-road conditions.
� Revised, sophisticated Inverted Twin-Chamber Cartridge Fork (see Technology Section).
� Pro-Link� Rear Suspension with new damper settings (see Technology Section).
� Large 50mm diameter for rear shock damper piston for consistent performance under demanding riding conditions.
� HRC works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating the need for a separate reservoir and hose assembly.
Additional Features
� Rider ergonomics are optimized by adapting the handlebar, seat and footpeg height to place the rider's legs at the narrowest frame width for improved comfort and handling feel.
� Rear brake pedal and shift lever are made of lightweight aluminum and are designed to complement the riding position. Brake pedal features optimized ratio to match integrated rear-brake master-cylinder design.
� Wide, cleated, stainless-steel footpegs are self-cleaning, resist corrosion, provide excellent grip and fold for extra ground clearance.
� Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.
� Handlebar holders provide two different mounting positions to match rider preference.
� Works-type handlebar grips add to rider comfort.
� Adjustable front brake lever.
� Quick-adjust clutch.
� Chain-guide material offers improved wear resistance, and service life is five times greater than conventional materials.
� Front disc brake cover helps protect rotor and caliper from damage.
� Removable rear subframe allows easy maintenance.
� Washable, two-stage foam air filter for optimal engine protection and easy maintenance.
� Comfortable, durable controls and high-quality fasteners.
� Stainless-steel clutch cable for long life.
