Engine & Exhaust

4-strokes have taken motocross to unthinkable new extremes. It is a playground where KTM has become a dominant force. Lighter and more compact than ever thought possible, these well-balanced engineering masterpieces deliver class-leading power in the most dynamic way. Straight from the showroom floor, KTM 4-strokes offer READY TO RACE performance of the highest calibre.

Engine

Unrivalled power

…Renowned as the strongest engine in MX2 competition, the 2019 version pushes the boundaries of innovation even further. With updates on valve timing, exhaust, airbox and EMS, the entire power pack produces even more torque and power across the entire 14,000 rpm range. Its compact structure contributes to excellent mass centralization, which supports the easy ride-ability of the bike. The low weight of only 25.9 kg, in combination with the compact engine layout and unrivalled power, once again makes the new KTM 250 SX-F a real force to be reckoned with, yet still easy to ride for both amateur and professional riders.

Crankshaft

…The 250 SX-F's has a rigid crankshaft which features a connecting rod with a plain big end bearing featuring two force-fitted bearing shells run directly on the crank pin. This design is a major prerequisite for the extremely high engine speed levels and the unrivalled maximum power of the 250cc engine. Not only that, it enhances the engine's durability, allowing long crankshaft service intervals, which is a huge customer benefit in relation to time, effort and cost.

Crankcases and engine covers

…The compact engine cases are manufactured using a high pressure die-cast production process that helps with weight reduction, while retaining strength and durability. The design allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass centralization and easier ride-ability. Plus, the new engine covers feature a smart surface structure that reduces wear caused by the rider's boots, keeping them looking as fresh as the day you bought it.

Skid plate

…This generation of skid plates provides the most effective protection for the frame and engine: Made from 3 mm thick, high-strength and robust C-SMC material Extremely lightweight due to the material used Decoupled from the frame by rubber inlays Direct assembly on the frame Extremely durable and endurance tested for the toughest offroad use Perfectly tailored design Highest quality machining Quick and easy assembly

Cooling

Effective heat control

…Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 250 SX-F features newly designed radiators which are mounted 12 mm lower than the predecessors. This lowers the center of gravity and matches the design of the new shrouds perfectly, in order to achieve perfect ergonomics. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. The radiators also feature special protectors that don't only serve as protection from flying rocks and debris but also as a brace that disperses energy around the radiators in the event of an impact.

Radiator fan

…Indispensable in extreme conditions, this fan ensures more air, better cooling and maximum performance. It's in your own hands: The digital control allows you to adjust the switch-on temperature to the present conditions and to read off the current temperature at any time. The switch-on temperature can be set anywhere between 65°C and 95°C. The switch-off temperature is set automatically, and is always 1°C below the switch-on temperature.For installation on all models, you will need the auxiliary wiring harness 77711979000; for additional switching, the Y-distributor 77711979044 can also be installed.

Exhaust

Tuned for power

…When it comes to improved power delivery and performance, the new exhaust on all 4-stroke models play a key role and packs a punch that is hard to beat. It features a new, model specific header pipe with a further advanced resonator called FDH (Flow Design Header), which is a small chamber around the pipe. The silencer has a new profile aluminium sleeve and a new end cap, as well as a reworked internal design. The new shape allows the exhaust to be disassembled without removing the shock absorber and also provides better access to the shock. Another benefit of the new shape is slimmer ergonomics, making the bike feel narrower, without compromise to regulatory noise limits.
