450 XC-F XC-F
2023 KTM 450 XC-F, <br/> <p>The 2023 KTM 450 XC-F rolls into the pits already armed with the learnings of past championships - but now it's blistering with an all-new arsenal of weaponry. Being the leading 4-Stroke in the Cross Country division for the year, the KTM 450 XC-F once again brings its undeniable READY TO RACE spirit to the starting line with a relentless assault on the podium. A new frame, new rear shock, better electronics, and more performance all mean one thing - it's time to extend the trophy room.</p> <ul class=primaryProductFeatures>;</ul> Engine & Exhaust <ul class=itemGroupFeatures><li id=100438973 class=productFeature>Engine: The 2023 KTM 450 XC-F boasts one of the most manic 4-Stroke powerplants in the pits, with its SOHC engine proving to be the perfect example of advanced engineering. For 2023, the engine is tilted 2° backward with a lower sprocket position, which together with the benefits of mass centralization and reduced weight, makes the anti-squat behavior of the chassis second to none. With a massive peak power output and an overall engine weight of only 59 lb, you'll leave the competition with more than a little mud on the face.</li><li id=100438974 class=productFeature>Cylinder: The lightweight aluminum cylinder features a 95 mm bore and 63.40 mm stroke, housing a CP bridged-box-type piston weighing a meager 327 g. The piston features anodized annular grooves, adding durability and longer service intervals, with the compression ratio increased to 13.1:1 for added peak performance.</li><li id=100438975 class=productFeature>Cylinder Head: A completely redesigned SOHC cylinder head makes for a more compact and lightweight package, using a shorter profile with the camshaft located closer to the center of gravity. Lightweight valves are actuated via a DLC coated rocker arm with optimized timing, specifically designed to deliver precise levels of torque and throttle response. The diameter of the intake valves is 40 mm, while on the exhaust it is 33 mm. Redesigned intake ports allow higher flow coefficients, resulting in a more efficient and powerful engine, with a new valve cover reducing the number of mounting screws, and a single oil spray jet guarantees efficient cooling while keeping the weight low.</li><li id=100438976 class=productFeature>Throttle Body: An important update across the 2023 KTM XC range is an all-new 44 mm throttle body. Taking its learnings from the KTM Factory Racing machines, the injectors are positioned in a double-injector pattern to ensure the most efficient flow into the combustion chamber, while the throttle cable is mounted directly without a throttle linkage providing smoo
