SIX DAYS, SIX WINS

KTM celebrates its prowess in the world of offroad racing with the 450 EXC-F SIX DAYS. Built to perform under the toughest race conditions like those found at the Chilean ISDE, and boasting READY TO RACE componentry, it is well-equipped to take on anything thrown at it.

Motor og eksos

Motor og Eksos

The hugely successful KTM 450 EXC-F power plant has kept its key ingredients the same for 2019 – compact dimensions, relentless performance throughout the rev range and low weight. Fitted with a single overhead-camshaft cylinder head and the latest electronic fuel injection, it churns out horsepower in line with what you’d expect from a pure-bred factory race weapon.

TRANSMISSION

The reliable 6-speed transmission features a special surface treatment on the 2nd, 3rd and 4th gears for solid reliability. The advanced ´No Dirt´ gear shift lever design prevents dirt from jamming the joint of the lever and guarantees precise shifting even in the muddiest conditions. All 4-stroke EXC-F engines are fitted with a gear position […]

ENGINE MANAGEMENT SYSTEM

The state-of-the-art Keihin engine management system with electronic fuel injection features a 42mm throttle body. Thanks to its unique injector position, the engine’s response gives a whole new meaning to the word ‘instantaneous’. Separate circuits for cold-starting and idle make on-site adjustments easy. Push the throttle back when the engine is warmed up and the […]

E-STARTER

The KTM 450 EXC-F is fitted with a unique E-starter as standard, which is a clear advantage when it comes to crunch time in the heat of battle. A strong starter motor and a reliable lithium ion battery will fire up your 450 time and time again at the push of a button. To reduce […]

CYLINDER HEAD

A single overhead camshaft controls intake and exhaust through optimized ports, while a cutting-edge combustion chamber and water jacket create mind-blowing power while managing heat. The engine’s four valves rely on extremely rigid rocker arms. Double lateral brackets fix the engine to the frame and reduce vibrations.

CYLINDER AND PISTON

Inside the cylinder, with a bore of 95mm, thumps a forged box-type piston with an ultra-light piston pin. Its crown geometry is adapted perfectly to the combustion chamber, where its rigid structure and low weight shine. Thanks to low oscillating masses, the engine is as smooth as it’s powerful.

CRANKSHAFT

The KTM 450 EXC-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 (bottom) 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. […]

CRANKCASES AND ENGINE COVERS

The design of the die-cast crankcases 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 EXC-F will keep […]

CLUTCH

The KTM 450 EXC-F employs the KTM-developed DDS clutch (damped diaphragm steel) with a wear-free steel basket and extremely heat resistant clutch plates and nitrated steel liners. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. A diaphragm spring also leaves sufficient space for a […]

BALANCER SHAFT

To balance the mass forces, the KTM 450 EXC-F engine uses a multifunctional, side-mounted balancer shaft, which at the same time drives the water pump. It has been balanced to perfection, keeping vibration levels to a minimum, even while gunning it to the maximum.

Chassi

Chassi

Just like the rest of its SIX DAYS brethren, the 450 EXC-F SIX DAYS shares a race-winning chassis setup. WP suspension keeps the wheels planted, while weight-saving efforts and performance-orientated materials ensure riders and racers are well-looked after on the trail or on track.

WHEELS

The EXC-F’s wheels feature lightweight, CNC machined hubs and high-end Giant rims guaranteeing maximum stability at minimum weight. The wheels are fitted with MAXXIS tires – perfect for surefooted performance off-road and stability on-road.

TRIPLE CLAMP

All Six Days models are fitted with high-end CNC machined triple clamps anodized in orange and an offset of 22mm, ensuring a solid grip of the fork and precise handling. The handlebar is adjustable forwards and backwards over 4 positions, so the bike will fit you like your favorite gloves.

SWINGARM

This state-of-the-art swingarm allows for an optimized mounting position of the PDS shock absorber, providing more progressive action. Furthermore, the cast aluminum design guarantees lower weight and a perfect flex behavior. The single-component casting process also eliminates any inconsistencies and weak points.

REAR SUSPENSION

The PDS is kind of a KTM trademark where the shock absorber is directly connected to the upper side of the swingarm. This setup boasts the best possible mounting geometry and provides amazingly progressive damping. The shock absorber is mounted close to the centerline, which means nearly symmetrical loads for the swingarm and frame and […]

FUEL TANK

The lightweight polyethylene tank has a capacity of 8.5 liters. You will always be able to see how much fuel remains at a glance, thanks to the see-through plastic. By pushing the orange release button in the center of the fuel tank cap, the bayonet mechanism makes refueling quick and easy. It is fitted with […]

FRONT SUSPENSION

The WP XPlor 48 upside-down fork is a split fork developed by WP in close collaboration with KTM. It is fitted with a spring on both sides but features separated functions for each fork leg: compression damping is fitted on the left side, while rebound is on the right. The forks can easily be adjusted […]

FRAME

The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on high torsional rigidity and low 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 […]

BRAKES

You can’t brake any harder, better, faster or stronger. High-tech Brembo calipers are combined with lightweight Wave brake discs. The steel-flex front brake hose has efficient protection and there’s an integrated channel for the speedometer cable. First you outrun them, then you outbrake them.

AIRBOX

The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow in a quiet way. 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 can pop a fresh one in […]

Ergonomi og komfort

Ergonomi og komfort

Enduro racing is all about tough, technical terrain and fast, wide-open straights. It goes without saying that riders need to be able to move about the bike freely. With that in mind, KTM has ensured that the same READY TO RACE ergonomics of 2018 has been retained for 2019.

SEAT

Tailored to meet the needs of the world’s fastest backsides, this durable seat offers great comfort, helping you master the most challenging terrain all day long.

HANDLEBAR

KTM engineers know how to handle handlebars. This tapered unit, made of high-strength aluminum by NEKEN, features a throttle assembly with a robust aluminum body and easy free-play adjustment. An ODI volcanized grip sits on the right, while on the left side of the bar a comfortable ODI lock-on grip requires no glue or wire […]

FOOTPEGS

Sophisticated ´No Dirt´ footpegs prevent jamming up of the pegs, even when digging in deep ruts. The pegs on the EXC models are 6mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.

Bodywork og dekaler

Bodywork og dekaler

Flying the Chilean colors for 2019, the plastics on the 450 EXC-F SIX DAYS share the same I-beam structure on its front and rear fenders as the rest of the multi-race winning enduro range. This guarantees maximum stability and low weight thanks to well thought-out construction and mounting points.

SIX DAYS EQUIPMENT

Six Days seat for improved long-distance comfort, Exclusive Six Days graphics with a striking design, Handlebar map select switch, Handlebar with Six Days logo, Six Days silencer (anthracite anodized and with Six Days logo), Machined orange anodized triple clamps for extremely precise fork clamping and optimum fork function, Radiator fan for all 4-stroke models to […]
