2016 KTM 450 XC-F Base

2016 KTM 450 XC-F

If maximum power is required, there is no other way but the 450 XC-F. The compact SOHC (single overhead camshaft) engine that delivers explosive but controllable power shares 95% of the parts with the bike of Ryan Dungey winning the AMA Supercross championship 2015.

• ENGINE

With new features such as more compact dimensions, stronger performance throughout the rev range and a weight reduction of 4 lbs, this newly developed powerplant is the lightest 450 engine on the off-road market. With a reworked single overhead camshaft cylinder head and the latest electronic fuel injection, the 450 XC-F has unrivalled power of more than 62 hp and a highly efficient power delivery.

• ENGINE CASES AND COVERS

The completely new design of the die-cast engine cases allows for a much more centralized shaft configuration, raising the crankshaft by 7 mm and 9 mm backwards to centralize mass and for a weight savings of 1.2 lbs. Newly designed engine covers made of magnesium feature an advanced surface structure in order to reduce the wear caused by the rider's boots.

• ENGINE MANAGEMENT SYSTEM

The completely reworked Keihin Engine Management System, with electronic fuel injection, features an all-new 44 mm throttle body, which provides instantaneous response and maximum performance thanks to a revolutionary injector position. The new ECU (Engine Control Unit) includes a launch control for more efficient starts with the provision of different maps according to the gear sensor selection. In addition, the rider can activate an optional map for a different power delivery via the map select switch on the handlebar.

• MONOSHOCK

The new generation of monoshock made by WP Suspension has been developed for the new XC models in conjunction with the new frame and swingarm architecture, including the reworked linkage system and the new WP forks. The new body features a revised reservoir for a larger gas chamber to reduce performance fade. The linkage system has also been reworked with a revised geometry and longer pull rods.

• WEIGHT REDUCTION

The main target for the KTM engineers when developing the new XC-F generation was a massive weight reduction in conjunction with improved handling. The resulting loss of nearly 8 lbs is outstanding, making the new KTM models the lightest bikes on the track, even with electric starting.

• HANDLEBAR

The new generation XC-F models are equipped with a new tapered handlebar made of high-strength aluminum by NEKEN, which is fixed in a new rubber damped handlebar clamp allowing the handlebar to be mounted in two different positions. All 4-Stroke models feature a new throttle assembly with model-specific throttle cams for different opening characteristics and new ODI grips featuring lock-on fixing clamp on the left-hand side. In addition the handlebar-mounted map switch allows easy selection of different maps and the activation of a launch control.

• COOLING SYSTEM

The proven integrated KTM cooling system routes the coolant from the cylinder head through the frame triangle, directly to newly developed aluminum radiators made by WP, which have a new filler cap system and are made of a stiffer alloy. Due to flow-optimized internal circulation and CFD-calculated air ventilation, the cooling efficiency has been improved by approximately 10 %. Sophisticated radiator guards provide efficient protection in case of crashes.

• WHEELS

The 450 XC-F is fitted with lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight aluminum nipples providing maximum stability at minimum weight. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
