KTM 450 EXC Six Days
The 450 EXC is "ready to race " for the world's largest enduro competition, the "International Six Days Enduro". Six days in succession, over a thousand offroad kilometres, 40 hours in the saddle - a gruelling test, not only for the rider. A whole package of high-quality special options makes the 450 EXC fit for this ruthless contest, in which more than half the starters bank on KTM every year. 450 EXC Six Days - the genuine article with the orange powder-coated frame of the KTM Factory Team.
KTM 450 EXC Six Days Features and Benefits
WITH EXCLUSIVE OPTIONAL EQUIPMENT

NOW EVEN MORE ERGONOMIC
The 450 EXC's new bodywork with the very slim seat and spoiler lines, plus excellent contact points, perfects the bike's ergonomics, making handling even simpler and more precise. The longer rear fender protects the rider even more effectively from swirled up stones.
NOW WITH EVEN MORE PERFORMANCE
With the 450 EXC's newly developed engine, KTM engineers have created a new dimension: The power unit has been redesigned from scratch and is now more compact, lighter and more powerful than before. Reduced reciprocating weight and a balancer shaft minimise vibration.
The newly developed Keihin engine management system with electronic fuel injection ensures spontaneous responsiveness from the engine. Various engine characteristics can be activated with an optional map select switch.
NEW OIL CIRCUIT
The 450 EXC's new engine is equipped with a common oil circuit for engine and transmission, and two oil pumps. A pressure pump lubricates the engine, while a suction pump draws oil from the crankcase, using it to lubricate the transmission and the clutch. At the same time and in conjunction with a steel diaphragm, negative pressure arises in the casing, which boosts the engine power.
NEW BALANCER SHAFT
The 450 EXC's new, more compact balancer shaft not only eliminates vibration, but also serves as the drive for the water pump. This intelligent multi-functionality contributes to the compactness and low weight of the 450 EXC's new engine.
NEW ENGINE CASE
The 450 EXC's new engine case weighs almost 2 kg (4 lb.) less than its predecessor, although it offers better resistance to damage due to stone impact or falls. This has been achieved by using a high-strength, elastic aluminium alloy and changing from sand-casting to die-casting.
When designing the new crankshaft on the 450 EXC, KTM engineers focussed on reducing the reciprocating weight. Thanks to the new, lighter connecting rod and the new, lighter piston, they managed to achieve minimum vibration, while maximising engine-speed strength.
NEW CYLINDER AND PISTON
The 450 EXC's cylinder has been further developed especially for the new engine configuration. The new, 15 % lighter forged piston minimises reciprocating weight and optimises durability at high engine speeds. New, nitrided piston rings ensure highest levels of resistance to wear.
NEW CYLINDER HEAD
All ports and the combustion chamber have been redesigned in the OHC cylinder head of the 450 EXC's new engine. The new camshaft actuates four valves via lightweight rocker arms. High-quality titanium valves are used on the intake side. As before, the cylinder head cover mounted at an angle simplifies service work.
The 450 EXC's new, improved silencer featuring a special Six Days coating not only offers greater volume and a new design, it also reduces noise levels to the stricter standards of the future.
The 450 EXC's newly developed clutch, with a robust steel cage and transmission-friendly back-damping, makes use of a spring washer for the first time instead of the customary conical springs, hence substantially reducing the operating force. The hydraulic actuation mechanism from Brembo® facilitates sensitive modulation of the clutch.
NOW WITH AN EVEN MORE SUPERIOR CHASSIS
The completely revamped frame made from high-quality chrome-molybdenum steel is characterised by even greater lateral stiffness. Furthermore, it is even better at absorbing jolts introduced by the suspension system, whereby the simple handling and comfort of the 450 EXC have been further optimised.
NEW SWINGARM, NEW PDS, NEW SETTING
The 450 EXC's new, lighter, cast aluminium swingarm accommodates the shock absorber more centrally, in order to load the swing arms more evenly. The new, 7 mm (0.28 in) longer PDS shock absorber with adjustable rebound and high/low-speed compression damping, and a new setting is installed more flatly, so providing even more progression.
TELESCOPIC FORK, NEW SETTING
The 450 EXC is equipped with the latest WP upside-down fork with wider adjustment ranges and a new setting. The sensitive responsiveness and outstanding damping of the open-cartridge fork with 48 mm (1.89 in) outer tubes are a perfect complement for the 450 EXC's simple handling and precision.
Practically unbeatable in terms of weight and stability, the new wheels have CNC-machined hubs, new black-anodised rims from Giant, black zinc/nickel-coated spokes and ultra-light aluminium nipples. They reduce the unsprung and gyroscopic masses, hence bolstering the simple handling of the 450 EXC.
