2016 KTM 450 SX-F, 2016 KTM 450 SX-F Holeshot Bragging Rights If maximum power is required, there is no other way but the 450 SX-F. This model has proven itself in the main championships around the world over the years. Thanks to its compact SOHC (single overhead camshaft) engine that delivers explosive but controllable power, it is the weapon of choice for the US KTM Factory Team and Ryan Dungey winning the AMA Supercross championship 2015. Features May Include: FRAME The new frame design provides approximately 20 % higher torsional rigidity and 30 % less longitudinal stiffness, with newly designed engine stays for less vibration. This increased flexibility results in better absorption of the energy created from the front and rear wheel loads supporting the suspension for more comfort and less rider fatigue. A 0.4° steeper steering angle and a 10 mm shorter wheel base contribute to better handling and last but not least it´s around 380 g lighter than the previous model. SWINGARM As on the predecessor models, the new SX generation features a reworked cast aluminium swingarm. The updated design offers reduced weight and an optimized flex behavior supporting the frame and suspension created with a single-component casting process. The weight reduction is 250 grams. MONOSHOCK The new generation of monoshock made by WP Suspension has been developed for the new SX models in conjunction with the new frame and swingarm architecture, including the reworked linkage system and the new WP forks. The linkage system has also been reworked with a revised geometry and longer pull rods, which was tested last season in most of the KTM factory bikes. FORKS The KTM SX models are fitted with a revolutionary new and super-lightweight WP fork, a 48 mm USD air-sprung fork developed by WP Suspension in close collaboration with KTM. It is a split fork with separate functions for each fork leg. The damping functions are on the right side, whereas the air spring is in the left. The left leg features a capsuled air cartridge. This air spring is easy to adjust to any rider weight via a single air valve and a standard fork air pump. The right fork leg integrates a completely new damping cartridge to fit single damping leg requirements, and the damping can be adjusted to the track conditions or the rider s preferences with a twist of a dial. The new fork with approximately 300 mm travel has outstanding response and excellent, very consistent damping characteristics, while also with a reduced weight of 1.4 kg compared to its predecessor. ENGINE With new features such as its much more compact dimensions, stronger performance throughout the rev range and a weight reduction of 1.8 kg, this newly developed powerplant is the lightest 450 engine on the MX market. With a reworked single overhead camshaft cylinder head and the latest electronic fuel injection, it is dist
2016 KTM 450 XC-F, 2016 KTM 450 XC-F Holeshot Bragging Rights 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. Features May Include: 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-
