2020 KTM 450 SX-F Factory Edition

 

From KTM: We build and race Factory Editions. Championship winning bikes, like this one. Thanks to its compact SOHC (single overhead camshaft) engine delivering explosive but controllable power, it is the force behind the success of Red Bull KTM Factory Teams around the world. A lightweight chassis and a slim bodywork put the KTM 450 SX-F Factory Edition ahead of the competition. A long list of special equipment such as a factory installed holeshot device, a floating front brake rotor and a slip-on Akrapovic muffler add to the arsenal that ensure this limited edition model cannot be rivaled. The Factory Edition is a proven formula for success.

Engine & Exhaust
KTM's hugely successful 450cc SOHC engine is known as the lightest and most powerful on the market. A compact design contributes to maximum mass centralization for better handling. Featuring several more features than the standard model, the KTM 450 SX-F Factory Edition produces an unrivaled power and rideability, capable of shooting both pros and amateurs alike to the top of the podium.

   • Engine - The 450cc engine is the ultimate powerhouse when it comes to KTM's competitive motocross range. Its compact, lightweight design features a single overhead camshaft cylinder head, fueled by a highly advanced electronic injection system. This enables the impressive power to be distributed extremely efficiently throughout the rev range. Even with its super-beneficial electric starter, this model is still the lightest 450 cc engine on the MX market.

   • Cylinder head - The KTM 450 SX-F is fitted with a lightweight, compact SOHC (single overhead camshaft) cylinder head. 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 33mm) are activated via extremely rigid rocker arms. The rockers on intake side are DLC coated, allowing for impressive engine speeds up to 11,500rpm. Low-friction chain guides further support the high RPM levels. The innovative head configuration guarantees the most efficient delivery of the unrivalled power, keeping 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 ride-ability. 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 ride-ability. 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.

   • Cooling - Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 450 SX-F features radiators which are positioned for a lower the center of gravity. Their design matches the shrouds perfectly and offers a great slim feel to the 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.

   • Exhaust - The header pipe features a flow-designed resonance chamber that is seamlessly integrated into the system for low noise and optimal power delivery. The lightweight slip-on AKRAPOVIČ muffler delivers excellent performance , while ensuring noise levels comply with competition requirements.

Chasis
The chassis on the KTM 450 SX-F Factory Edition is known for its easy handling and excellent stability. The stiffness of the frame is designed to improve bump absorption, while its CNC-machined Factory triple clamps benefit both handling and fork action. High quality WP suspension completes the overall package, ensuring the KTM 450 SX-F Factory Edition is an unstoppable force in any situation.

   • Frame - The frame on the KTM 450 SX-F Factory Edition is made of professionally crafted hydroformed Chromium Molybdenum steel tubes which are robot welded for the highest levels of consistent quality and strength. The frame stiffness is designed for optimal handling, comfort and high-speed stability. The orange powder coated frame is fitted with color matching frame protectors and a carbon fiber reinforced skid plate.

   • Swingarm - The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding.

   • Wheels - The KTM 450 SX-F FACTORY EDITION is fitted with high-end Factory Wheels. They feature black D.I.D DirtStar rims and fully CNC-machined orange anodized hubs. Together with black spokes and orange anodized aluminum nipples, they guarantee minimal weight at maximal stability so that the rider will feel an increase in handling. Dunlop GEOMEX MX3S tires put the power to the ground using the proven block-within-a-block design.

   • Brakes - A 260mm floating front brake rotor is matched to a Brembo master cylinder and caliper for class-leading stopping power and feel. A front brake protector is fitted as standard equipment on the 450 SX-F Factory Edition.

   • Fuel tank - A lightweight polyethylene tank with a capacity of 1.85 gallons. The fuel tank cap has an inside thread, which makes for quick, easy and reliable closure.

   • Airbox - The airbox design offers maximum protection of the air filter while ensuring maximum airflow. The large twin-air filter is mounted in a stiff cage, which helps to hold the system securely in place. This design is so simple, you can pop a fresh one in without tools, in seconds

   • Front suspension - The WP XACT 48 with its innovative AER technology, is a split function fork featuring a capsulated air spring and pressurized oil chamber for consistent and progressive damping, while offering supreme adjustability. Air spring adjustment is simple with the factory supplied WP digital air pump. The fork features an updated suspension hardware and a new setting, in addition it is fitted with a mechanical holeshot device on the right fork. This ensures the proper weight distribution and ride height for getting to the first turn ahead of the competition.
