2018 KTM 450 SX-F FACTORY,

We Don't Just Build Replicas;

;

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 weapon of choice for Red Bull KTM Factory Teams around the world. A revised chassis, a more compact cylinder head and slimmer bodywork put the 2018 450 SX-F FACTORY EDITION even further out front of the competition. A long list of special equipment such as a factory installed holeshot device, a floating front brake rotor and a billet clutch cover just add to the arsenal that raises this limited edition model to level that cannot be rivaled. With three consecutive AMA Supercross Championship victories, it is clear the FACTORY EDITION is a formula for success.

• KTM’s hugely successful 450cc SOHC engine is already known as the lightest and most powerful on the market, but KTM’s engineers did not rest on the laurels of this epic engine. A new more compact and lighter cylinder head drops the overall height of the engine by 15 mm for better mass centralization and better handling. Fitted with the latest fuel injection technology and engine management, the 450 SX-F FACTORY EDITION produces unrivaled power and rideability that will shoot both pros and amateurs alike to the top of the podium.
• Cylinder head: At 15mm lower than the previous generation, the redesigned cylinder head puts the camshaft closer to the center of gravity of the 450 SX-F FACTORY EDITION. The cam features a new surface treatment and rides on low-friction DLC rocker arms to actuate lightweight titanium valves.  A low-friction cam chain completes the highly efficient and compact valve train.
• Crankshaft: The crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big-end bearing with two force-fitted bearing shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’s pressurized lubrication. This design is a decisive benefit in terms of the crankshaft service interval, which can be lengthened due to the plain bearing.
• Crankcases and engine covers: The design of the die-cast engine cases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, w
