Digital Fuel Injection (DFI) System

• New finer-atomizing Downstream Fuel Injector and revised ECU settings
• The dual injectors are fine-atomizing injectors with four holes. The upstream injector has a droplet size of 120µm, while the new downstream injector is 75µm. The finer size and wider spray pattern contributes to a stronger low- to mid-range power, improved response and quicker acceleration.
• Intake tract design provides optimal airflow from the airbox into the combustion chamber
• Seal between air inlet port and throttle position sensor unit on the 43mm throttle body protects TPS sensor from fuel penetration
• Progressive throttle linkage for sharp and precise throttle response across entire rpm range
• Simple and efficient system: No battery, fuses or relays
• Offers easy engine starting

Efficient Cooling System

• Thick radiators are strong and offer excellent resistance to mud buildup while providing superb cooling performance
• Cylinder head water jacket routes coolant to the front of the cylinder head for even cooling

Factory-Style Components

• Pushrod-type front brake master cylinder and brake pad material provide strong brake force and enhanced feel
• Rear brake pad material offers powerful braking performance
• Lightweight black anodized rims are durable and look just like the factory racers
• Titanium-coated inner fork tubes minimize stiction and look great
• Front and rear petal brake discs help reduce unsprung weight, and the wave shape helps clean the brake pads for more efficient stopping performance
• Rear caliper guard protects caliper from damage
• Ribless rear hub and butted spokes reduce unsprung weight
• Renthal aluminum handlebar is standard equipment
• New green anodized suspension adjusters, engine oil cap and generator cover plugs like the factory race bikes
• Factory-style graphics complement the KX250F’s performance

Factory-Style Launch Control Sytem

• The KX250F Launch Control was a first for the 250 class and increased the rider’s ability to get good starts by maximizing available traction
• Launch Control is activated by pushing a button on the left handlebar while stopped, in neutral, first or second gear
• Retards ignition timing in first and second gears, giving the greatest effect within the first few seconds of releasing the clutch
• Shifting into third gear automatically deactivates Launch Control Mode and returns the ignition to normal mapping
• Particularly effective when chasing the holeshot from concrete starting pads and other slippery surfaces

High-Reviving, High Performance Engine

• 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DOHC engine delivers hard-hitting power across the rpm range
• Nickel plating on the cylinder wall has a high adhesion factor for optimum durability
• Thick-stem connecting rod resists flex and enhances durability
• Upgraded crankcase oil jet delivers an optimized stream of oil to the underside of the new Bridged Box piston with short skirts and reinforced external ribs for increased strength.
• Thick crank web design features a balance factor on par with the factory racers to help minimize engine vibration, provide smooth power delivery and maximize performance in the mid-high rpm range

Lightweight and Efficient Top End

• Intake valve seat material offers increased durability
• Ultra-light valves have extremely thin valve stems on par with those found in supersport machines; intake valves feature thick heads for increased strength
• Special casting method leaves the intake port surfaces extremely smooth for optimum intake efficiency across the rev range
• Silicon-coated head gasket provides excellent sealing

Quick-Turning Chassis

• The KX250F’s slim and lightweight aluminum perimeter frame helps provide excellent ergonomics and handling
• Center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations designed to increase forward drive with minimal rear-end squat

Rider Interface

• New two-position, adjustable footpeg brackets allow rider to lower the position by 5mm, lowering the center of gravity.
• New four-position upper triple clamp with two sets of handlebar mount slots. These give the rider a choice of four bar positions, including 25mm forward, 15mm forward, standard or 10mm back to suit many sizes and styles of riders
• Bodywork components offer the rider a slim interface, making it easy for racers to feel comfortable and go fast
• Formed using a double-injection molding process, the shrouds offer a slim design
• Right side panel passageways help cool the silencer
• Flat design of the seat and tank allow freedom of movement
• Frame is wider at the ankles to offer better grip and narrows near the bend below the seat to allow a slim riding position
• Slim seat features polyurethane designed to be durable
• Seat has a slip-resistant top and side surface for good grip when seated and while standing
• 50mm wide (front-to-rear) footpegs offer superb grip and feel at the pegs
• Clutch cable boot features a large quick adjuster, making it easy for riders to adjust play in the clutch cable while on the fly
• Throttle grip has a one-piece collar that provides additional stability during throttle operation
• Grips have short barrels and are made from soft material to enhance rider comfort

Separate Function Fork

• Revised settings on the 48mm Separate Function Fork (SFF) delivers firm damping and increased ride control
• SFF design separates spring and damping functions for less weight, better performance, less stiction and easier adjustability compared to traditional forks

• Short high-volume muffler assists with mass centralization, makes good power, while large cross section restricts noise levels to an AMA race-legal 94dB.
• Durable stainless steel construction

Transmission and Shifting

• Transmission gears feature four dogs for smooth shifting
• Shift-fork grooves enhance feel at the shift lever
• Clutch cable holder is integrated with the crankcase for accurate feel at the clutch lever
• Scavenge oil filter screen can be accessed without splitting the crankcases, facilitating easier maintenance

Uni-Trak Rear Suspension
