  • Dual injector Digital Fuel Injection system
  • More robust high-rpm engine output extends deep into the overrev
  • Stronger engine components improve reliability

High-Revving, 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
  • 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

Digital Fuel Injection (DFI) System

  • Revised intake tract provides a straighter shot into the combustion chamber for more direct 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 opens more quickly after 3/8 open position
  • Simple and efficient system: No battery, fuses or relays
  • Sharp and precise engine response across entire rpm range
  • Offers easy engine starting
  • Helps prevent engine hesitation after landing from jumps and other high-impact situations

Bridged Box-Bottom Piston

  • Revised piston profile helps increase reliability
  • Light and strong piston shares same design as the factory racers, and a tin plating to optimize its interface with the nickel plating on the cylinder wall
  • Special finish improves surface lubrication and wear resistance
  • Short piston pin reduces reciprocating weight

Lightweight and Efficient Top End

  • Stronger 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

Stainless Steel Exhaust System

  • New 30mm shorter head pipe improves performance with a resonator chamber to help boost low-rpm torque
  • New high-volume muffler assembly is 30mm shorter with a larger cross section keeps noise levels at 94 dB while retaining power production
  • Durable stainless steel construction

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

Transmission and Shifting

  • Strong, beefy crankcases feature additional material around the engine mounts to help increase long-term durability
  • 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

Quick-turning Chassis

  • The KX250F’s slim and lightweight aluminum perimeter frame is 4mm narrower for improved 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

Upgraded SFF Fork

  • Upgraded 48mm Separate Function Fork (SFF) features new 1mm larger inner fork tubes which allow the internal damping components to be larger, for firmer damping response and increased ride comfort
  • SFF design separates springing and damping functions for less weight, better performance, less stiction and easier adjustability
  • Super-hard titanium coating on the outer surface of the inner fork tubes reduces stiction and improves suspension action while also helping prevent scratches and tube damage
  • Friction-reducing Kashima Coat treatment on the inside of the outer fork tubes contributes to smoother suspension action
  • Wrap-around fork tube guards provide excellent protection for the inner tubes
  • Revised lower triple clamp open at the back for increased rigidity and improved fork action

Uni-Trak® rear suspension

  • Rear shock features dual compression adjustability, allowing high-speed and low-speed damping to be tuned separately
  • Features Kashima Coat on the inside cylinder wall for reduced friction and smoother suspension action
  • New swingarm uses a longer cast front section, tapered hydroformed spars and forged chain adjusters
  • Uni-Trak® rear suspension linkage system mounts the suspension arm below the swingarm, allowing more rear suspension stroke and precise tuning
  • Linkage ratios for the Uni-Trak rear suspension match rear shock damping settings to achieve maximum rear wheel traction

Rider Interface

  • 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
  • New smaller side number plates also contribute to the slim package
  • Right side panel has an added passageway to help cool the silencer
  • Flatter design of the seat and tank offer greater freedom of movement

  • Slim seat features upgraded polyurethane, designed for greater durability
  • 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

  • New 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 further reduce unsprung weight
  • Renthal aluminum handlebar is standard equipment
  • Blue ignition cover plugs and oil filler cap match the blue accents on the factory race bikes
