Introducing the 2021 KTM 350 XC-FTaking lesson learned from Tony Cairoli’s dominating career aboard the 350 SX-F, and insights from top 350 EXC-F enduro riders, we created the KTM 350 XC-F. Sharing the same aggressive motocross personality but with a refined chassis setup, state-of-the-art motor internals and EMS, the 350 XC-F, like Tony, is a flat-out, offroad-ripping legend    CUTTING-EDGE 4-STROKES KTM refuses to knock down a gear in its mission to make the EXC-F models the most competitive 4-stroke machines on the market today.Low weight, unbeatable torque, efficient engine management, sensitive delivery, and even more reliability have been KTM development priorities over recent years. Developed for riders of any skill range, the 2021 KTM EXC-F models are race-winning machines across all offroad racing disciplines.ENGINE Compact dimensions with class-leading power output, KTM’s fuel-injected 4-stroke engines are the most refined and powerful on the market. They feature enduro-spec ific exhaust systems, latest-technology electronic fuel-injection, and several internal components that all help deliver efficient power throughout the rev range. These Euro IV homologated engines are the lightest and most competitive yet, with an unrivaled power-to-weight ratio.   ExhaustWhen it comes to power delivery and performance, the exhaust on all 4-stroke models plays a key role and packs a punch that is hard to beat. It features a model-specific header pipe with an advanced resonator called FDH (Flow Design Header), which is a small chamber around the pipe. The design allows the exhaust to be disassembled without removing the shock absorber and also provides better access to the shock. The aluminum sleeve, end cap and internal design of the silencer allow for slimmer ergonomics, making the bike feel narrower, without compromise to regulatory noise limits.EngineThe engine of the KTM 350 XC-F features a compact and very light (60 lbs) construction. Its DOHC (double overheard ca mshaft) design with lightweight titanium valves and DLC coated cam followers allows for lively but strong engine characteristics. Fitted with the latest electronic fuel injection system and an E-starter, it has an extremely wide usable speed range, high performance and incredibly efficient rideability. The KTM 350 XC-F engine shares the same layout as the 250 XC-F, resulting in playful handling that is similar to a 250 machine.AirboxThe airbox on the KTM 350 XC-F ensures optimal flow dynamics, and together with the intake snorkels, results in optimal power and throttle response. Despite the obvious performance enhancements, the design also offers maximum protection against soiling of the air filter. The large Twin-Air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools a standard, original feature from KTM.FrameThe high-tech, lightweight chrome-moly st eel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on precisely calculated stiffness of the frame. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight aluminum engine head stays (the connection between cylinder head and frame) contribute to more precise cornering and a reduced vibration level. The engineers were able to pull off all that, while making their frame 2.2 pounds lighter than that of the lightest competitor on the market. In addition, it 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 subframe made of aluminum, which tips the scales at less than 2 pounds.SeatErgonomically perfect, the seat has a high foam volume, which offers great comfort and durability, while keepin g the weight low.HandlebarAll KTM XC models are equipped with the same high-strength aluminum tapered NEKEN handlebar. The handlebar allows for four different positions. The handlebars come standard with an ODI vulcanized grip on the right side and a comfortable ODI lock-on grip, which does not require any wire or glue, on the left. Additionally, the bike is fitted with a map-select switch on the handlebar for selecting alternative engine maps. The rider also has the option to activate TRACTION CONTROL from this switch; a unique feature which guarantees more efficient traction, especially in slippery conditions, and can be activated with the push of a button during riding.FootpegsSophisticated 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 EXC models, which are 6 mm higher than the XC versions.SeatErgonomically perfect, the seat has a high foam volume, which offers great co mfort and durability, while keeping the weight low.HandlebarAll KTM XC models are equipped with the same high-strength aluminum tapered NEKEN handlebar.
