2017 KTM SX 450 F

2017 KTM 450 SX-FDROP THE HAMMERIf gold is what you’re after, a 450 SX-F is what you get. Thanks to its compact engine delivering explosive but controllable power, it’s the weapon of choice for the Red Bull KTM Factory Team and the champion, Ryan Dungey. This READY TO RACE bike rules the AMA Supercross Championship. Its secret? Precise handling and arm-stretching grunt. Winners - line up here.Features May Include:100.2 KGKTM engineers just love dropping weight year after year. The result: the 2017 SX models are the slimmest, lightest dirt bikes out there - even though the 4-strokes are equipped with an electric starter as a standard feature, while the competition still needs to be kickstarted. You can just focus on kicking ass.AIRBOXThe airbox design offers maximum protection of the air filter while ensuring maximum airflow. The large twin-air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a face full of mud. Without tools. In seconds.FRAMEThe high-tech, lightweight chrome-moly steel frame is engineered for excellent handling, precise cornering and supreme stability. You can also count on high torsional rigidity and low longitudinal stiffness for better absorption of the energy created by the front and rear suspension sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight engine head stays contribute to a reduced vibration level. Two threaded inserts in the lower cradle tubes allow for an optional skid plate. The engineers were able to pull off all that, while making the frame two pounds lighter than that of the lightest competitor on the market. In addition, the frame is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light aluminum subframe, which weighs in at less than 2 poundsFOOTPEGSSophisticated ´No Dirt´ footpegs prevent clogging of the footpeg pivot, even when digging in deep ruts. Looking for a higher riding position? Then just mount the footpegs of the MY2017 EXC models, which are 6mm higher than the SX versions.HANDLEBARKTM engineers sure know how to handle handlebars. This tapered one, made of high-strength aluminum by NEKEN, is fixed in damped rubber mounts and has two different positions. From 2017 onwards, the lower handlebar clamps are separated, while on the upper side a new bridge-type clamp guarantees more torsional stiffness. It’s also easier to replace the bar in case it gets twisted in a nasty crash. ODI lock-on grips make grip changes easy which does not require any wire or glue to be secured.SWINGARMThe cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It’s better looking too.EXHAUSTNoise limits are a real challenge for every manufacturer. Therefore, KTM has put a lot of effort into the development of its exhaust systems. All 4-strokes are fitted with header pipes that have a unique standard feature; an additional resonator system – a small chamber connected to the pipe. For the 450 SX-F the engineers developed an even more advanced version called FDH (Flow Design Header) that provides better engine performance and reduced noise. All 4-strokes are fitted with a short silencer, mounted as close to the engine as possible for mass centralization and better rideability. Its advanced internal design reduces the noise sufficiently in order to sit safely below noise limits while still raising the hairs on your neck.
