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.
