KTM FACTORY EDITION DETAILS

The 250SX-F and 450SX-F Factory Editions were unveiled in advance of the 2015 Supercross season and are almost entirely different from the standard models. The frames are still steel but have entirely different dimensions. The engines have almost nothing in common with their predecessors. The driving force behind the redesigns was weight loss. The 450 is said to be 10 pounds lighter than the standard model. The 250’s weight loss is claimed to be 7 pounds. There will be a limited number available to the public through the KTM dealer network. The price for the 450 will be $10,199 and the 250 will be $9299. Here is the information provided by KTM:

450SX-F FACTORY EDITION

• The new 450 SX-F engine design is more compact, lighter and provides

higher performance throughout the entire range of power

• New engine cases redesigned to centralize the rotating mass of the crankshaft

and clutch and reduce overall length by 23mm and width by 23mm

• Completely reworked Keihin Engine Management System with new 44mm

throttle body featuring a lightweight direct-connect design

• New electronic Launch Control and multiple engine maps to control the overall power delivery

• New cylinder head combustion chamber geometry, optimized ports, shorter timing

chain and friction reduced chain guides for improved power and reduced weight

• New 6mm shorter cylinder, lightweight piston connected to a shorter

con-rod and a crankshaft with 10% more inertia contribute to the

compact design, light engine feel and massive power

• New lighter 5-Speed transmission that is 8mm narrower and features a

new surface treatment on 1st and 5th gears along with a special lowfriction

coating on the shift forks to provide precise and easy shifting

• DDS (Damped Diaphragm Steel) clutch has a new lighter basket

along with a reworked inner hub and pressure plate providing

better oil supply and improved cooling of the clutch

• New super compact and lightweight 1.1lb Lithium-Ion starter battery

• New WP flow optimized radiator features a substantial improvement in engine cooling

• New Flow Design Header (FDH) with an integrated sound resonator that is

also designed to increase power along with a new lightweight silencer that

is 40mm shorter than the previous design for quick throttle response

• New airbox and airfilter design offers maximum protection for the engine while ensuring maximum airflow and providing quick “no tools” airfilter changes

• New ergonomics and bodywork to centralize mass, improve handling

and rider comfort

• The new 2015 450 SX-F Factory Edition weighs only 226.2lbs / 102.6kg

KTM 250SX-F FACTORY EDITION
