The design focusses on mass centralization, contributing to overall handling excellence. The overhead camshaft has a friction-optimized surface and valve timing that delivers impressive responsiveness. The four ultra-lightweight titanium valves (intake 40 mm, exhaust 33 mm) are activated via extremely rigid rocker arms. The rockers on the intake side are DLC coated, allowing for impressive engine speeds to 11,500 rpm. Low-friction chain guides further support the high RPM levels. The innovative head configuration guarantees the most efficient delivery of the unrivalled power, maintaining a strong edge over the competition.
  • CRANKSHAFT The crankshaft on the KTM 450 SX-F is located in an ideal position close to the center of gravity, contributing to better mass centralization. It utilizes a short connecting rod, which allows for a compact motor design and a snappier power delivery. The whole unit is extremely well-balanced, with the perfect amount of inertia for optimal traction and rideability. A plain big end bearing with two force-fitted bearing shells runs directly on the crank pin, with the necessary oil feed for this bearing supplied by the engine's pressure lubrication. This design also enhances durability, allowing for long crankshaft service intervals - resulting in less effort and cost and more time spent on two wheels.
  • 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 better mass centralization and easier rideability. The 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.
  • TRANSMISSION The transmission on the KTM 450 SX-F is focused on lightweight performance without compromise to durability. There was no need to change the gear ratios as they have been perfectly matched to the power delivery of the large displacement engine, but the secondary drive (sprockets) ratio has been made shorter (13/49) for improved response. All four-stroke engines are fitted with a gear sensor, which provides the option of different engine characteristics for each gear, depending on engine load. An advanced "no-dirt" gear lever design prevents dirt from building up and together with the reliable gearbox, guarantees that the next gear is always an easy click away.
  • ENGINE MANAGEMENT SYSTEM The state-of-the-art KEIHIN Engine Management System, with electronic fuel injection, features a 44 mm throttle body. The injector position guarantees optimal atomization of the fuel and air on the way to the combustion chamber, resulting in instant response and maximum performance when opening the throttle. There are also separate systems for cold starting and idle adjustment. The ECU features maps which have been developed to precisely match the exhaust and cylinder head, with options for regulating traction and launch control. It also provides different maps for each gear, according to the information received from the gear sensor, ensuring maximum power as you shift through the gears.
  • CYLINDER AND PISTON The 95 mm bore cylinder houses a newly-shaped, lightweight piston, made to the very highest standards by CP, delivering improved performance and reliability. Its design contributes to the engine's low vibrations and overall engine speed strength. Due to the low oscillating masses, the engine is not only powerful, but also displays extremely lively characteristics.
  • BALANCER SHAFT The multifunctional side-mounted counterbalance shaft masterfully balances all the oscillating forces, while also driving the water pump. It effectively keeps engine vibrations to a minimum, resulting in the smoothest ride, even at the highest engine speeds.
  • CLUTCH The KTM 450 SX-F is fitted with the extremely durable, KTM-developed DDS clutch (damped diaphragm steel), with a wear-free steel basket and heat-resistant clutch plates. It uses a diaphragm spring instead of the usual coil springs, which results in considerably easier clutch action. The diaphragm spring is also compact enough to allow for a damping system to be integrated into the clutch hub, contributing to better traction and durability. Additionally, the BREMBO hydraulic system provides easy and precise clutch modulation.
  • E-STARTER The standard electric starter on the KTM 450 SX-F uses a proven starter drive and a strong starter motor made by Mitsuba. As demonstrated time and time again, it provides quick and reliable starting, saving you precious time and energy when you need it most.
  • HANDLEBAR MAP SELECT SWITCH Within easy reach of the left grip on all four-stroke models, is a multifunctional handlebar map switch, which features the innovative control functions; traction control; launch control and alternative power curves (standard <-> advanced). The TRACTION CONTROL is a unique feature that guarantees more efficient traction and better control when accelerating the bike, especially in challenging track conditions. It can be activated on the handlebar map switch while riding. With a simple push of two buttons at idle speed, the rider can also activate LAUNCH CONTROL, ensuring the most effective launch out of the gate. The map switch also gives the rider the chance to select an alternative power map besides the standard configuration, providing performance options during the race.

CHASSIS

  • CHASSIS The KTM 450 SX-F delivers metal twisting torque and requires a strong frame to handle its immense power and speed.
