Overview

Description

A Formula For Success: 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 lightweight chassis and a slim bodywork put the 450 SX-F FACTORY EDITION 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 new slip-on AKRAPOVIČ muffler add to the arsenal that raises this limited edition model to a level that cannot be rivaled. The FACTORY EDITION is a formula for success.

Engine & Exhaust
  • KTM's hugely successful 450cc SOHC engine is already known as the lightest and most powerful on the market. A compact design contributes to maximal mass centralization for better handling. Featuring several updates compared to the standard model, 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.

The cam features a special 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.

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.

This makes the engine short and compact, while contributing to an efficient centralization of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider's boots.

Thanks to flow optimized internal circulation and CFD-calculated ventilation, the system is superbly efficient. In addition, well thought-out radiator guards integrated in the front part of the shrouds provide protection in a crash.
  • The header pipe features a flow-designed resonance chamber that is seamlessly integrated into the system for low noise and optimal power delivery. The new slip-on AKRAPOVIC muffler delivers excellent performance due to its low weight and noise levels that comply with competition requirements.…The header pipe features a flow-designed resonance chamber that is seamlessly integrated into the system for low noise and optimal power delivery.

Chassis Features
  • The chassis of the 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 the new CNC-machined FACTORY triple clamps benefit both handling and fork action. Updated WP Suspension settings complete a package that ensures the 450 SX-F FACTORY EDITION is an unstoppable force in any situation.
  • 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.…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.
