FLOAT LIKE A BUTTERFLY

ELECTRIFYING

KING OF COOL

  • ENGINE

    The hugely successful 450 SX-F powerhouse has extremely compact dimensions, strong performance throughout the rev range and a low weight; this is the lightest 450 engine on the MX market. But that doe...

    ...sn’t mean it’s not a heavyweight in terms of muscle. Fitted with a single overhead camshaft cylinder head and the latest electronic fuel injection, it pumps out an unrivaled 62hp. With KTM’s engineers working tirelessly to increase service intervals, this super stroker has the latest engine management technology on board and confidently shoots both amateurs and pros to the top of their time sheets.

  • CYLINDER HEAD

    Inside the SOHC cylinder head, an overhead camshaft controls the gas flow through the ports. This activates four ultra-lightweight titanium valves via extremely rigid rocker arms, which are DLC-coated...

    ... on the intake side. A configuration like this allows engine speeds of up to 11,500rpm; a baffling figure for a large displacement thumper. New lateral brackets, made of aluminum instead of steel, allow an efficient fixation of the engine to the frame and contribute to the bike’s featherweight.

  • CRANKSHAFT

    The 450 SX-F’s crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big-end bearing with two force-fitted bearing...

    ... shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’s pressurized lubrication. This design is a decisive benefit in terms of the crankshaft service interval, which can be lengthened due to the plain bearing. So rest assured and pin it, all day long.

  • ENGINE CASES AND COVERS

    The design of the die-cast engine cases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, while contributing to an efficient centralization...

    ... of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider’s boots. This way, your gem will keep on shining as it did on the day you bought it.

  • TRANSMISSION

    The 450 SX-F uses a lightweight 4-speed gearbox with gear ratios that are perfectly matched to the power delivery of its large displacement engine. The 1st and 3rd gears are treated with a special sur...

    ...face coating for better reliability. An advanced ´No Dirt´ gear lever design prevents mud and sand from blocking the joint of the lever and guarantees safe shifting. All 4-stroke engines are fitted with a gear sensor, giving the option of different engine characteristics for each gear. On the US market, the 450 SX-F is delivered with a 5-speed gearbox in order to leave the rest in your wake out in the desert.

  • ENGINE MANAGEMENT SYSTEM

    The state-of-the-art Keihin Engine Management System with electronic fuel injection features a 44mm throttle body. Thanks to its unique injector position, the engine’s response is instantaneous. And t...

    ...ad of the usual coil springs, which makes for a considerably easier clutch action. A diaphragm spring also leaves sufficient space for a damping system to be integrated into the clutch hub. The goal was traction, yes, but durability as well. On top of that, it is fitted with a lighter basket, a reworked inner hub and a pressure plate providing better oil supply and unsurpassed cooling. Of course, light operation and telepathic amounts of control are what makes this particular clutch, a hydraulic Brembo clutch.

    ...ow longitudinal stiffness. 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 a big fat kilogram 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 stable aluminum profiles, which tiptoes the scales at less than 900g.

    FIM noise limits are a real challenge for every manufacturer. Therefore, KTM has put a lot of effort into the development of their exhaust systems. All 4-strokes are fitted with header pipes that have...

    więcej

    ... 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. Speaking of which: all 4-strokes are fitted with a short silencer, mounted as close to the engine as possible. You know what that means: extra mass centralization and better rideability. Its advanced internal design reduces the noise sufficiently in order to sit safely below the FIM noise limit (112 dB(A) at 2 meter max.), while still raising the hairs on your neck.

  • HANDLEBAR

    KTM engineers sure know how to handle handlebars. This tapered one, made of high-strength aluminum by NEKEN, is fixed in damped rubber mountings and has two different positions. From MY2017 onwards, t...

It’s also easier to replace the bar in case it gets twisted in a nasty crash. An ODI volcanized grip sits on the right, while on the left side of the bar a comfortable ODI lock-on grip is mounted, which does not require any wire or glue to be fixed.

  • SWINGARM

    ... on the right side, whereas the air spring is in the left. This left leg features a two-chamber system with a capsuled air cartridge to prevent loss of air pressure. Should the outer seal start to leak, the internal cartridge pressure will keep the bike in position. The air spring is easy to adjust to any rider weight via a single air valve. No special tools are required; the air pump supplied with the bike will do just fine. The right fork leg integrates a damping cartridge that tailors to all your damping needs. It can be adjusted to the track conditions and the rider’s preferences with a twist of a dial (compression from the top, rebound from the bottom, 30 clicks each). For MY2017, the AER 48 also features redesigned outer tubes with better bending characteristics, smoother operation and less friction. Plus: they’ve lost some weight (265g). Right off the dealer floor, these forks are more comfortable and more sensitive than ever. But you can still hammer the hell out of them.

  • TRIPLE CLAMP

    Top quality, CNC machined triple clamps have been something of a KTM trademark for years. Ensuring a precise handling, they perceptibly support the flex characteristics, and with it the action of the ...

The rubber damped handlebar fixation has also been reworked and the lower handlebar clamps are now separated, while on the upper side a new bridge-type clamp guarantees more torsional stiffness and can easily be replaced in case it gets twisted due to a crash. In addition, an hour meter is fitted at the upper triple clamp in order to let the rider know it’s time for a service. Or a cold drink.

It guarantees more efficient traction and better control of the bike when accelerating. You’ll especially notice this on a rainy day. Push the button and reign supreme. With this map switch the rider can also activate the launch control, which provides more efficient starts out of the gate so you can go for the holeshot, time and time again. How? It simply reduces the maximum engine speed for the very first moment of the start, in order to give you better control. Push both buttons when the engine idles and the EFI control lamp mounted on the upper triple clamps will let you know your bomb is live. In addition, the map switch gives the rider the chance to select an alternative, more powerful map beside the standard configuration. Don’t you just love the idea of a boost button?
