01. Engine & Drivetrain
Tried and tested in series production, but tuned optimally to the KTM X-BOW RR: The manual 6-speed gearbox from Audi always has the right gear available. The Drexler limited slip differential that comes as standard guarantees optimum propulsion in every curve.
Graph of torque
The engine achieves its maximum torque of 420 Nm at an engine speed of only 3,200 rpm – thereby making, in the truest sense of the phrase, “very light work” of the KTM X-BOW RR, which tips the scales at a mere 810 kg. The maximum power output of 360 hp is attained at 6,400 rpm.
The aluminium spaceframe is the central supporting element for the engine/gearbox assembly. It has been possible to lower the whole unit by 19 millimetres, thereby lowering the KTM X-BOW R’s already impressively low centre of gravity by another 15 millimetres. As a direct consequence, even greater lateral acceleration forces and even higher cornering speeds are possible.
Shift lever with waterproof boot
Sporty gear lever with water-resistant shift boot.
The racing shifter delivers short and precise gear changes. Shortening the shifting movement allows better acceleration. The weight-optimised, aluminium console and the uniball-mounted gear lever guide provide the driver with ultra-precise shift-gate guidance and very accurate gear engagement.
High performance cooler
High-quality products, developed directly by KTM and manufactured in Austria: The high-performance radiators and charge-air cooler originate from WP Radiator.
Racing gearbox oil cooler
The racing gearbox oil cooler helps to keep the gearbox oil temperature at a constant level when using the KTM X-BOW in tough conditions on the racetrack. The radiator is available air cooled or coupled directly with the water cooling circuit of the engine.
Engine oil cooler extern
The engine oil cooler is a pure performance component that contributes to decreasing the load on the entire cooling circuit. The cooler is mounted externally behind the water coolers and the engine oil is transported to the cooler via a high quality motor racing feed orifice. The temperature of the engine is lowered through the external cooling of the oil in order to avoid a loss of power through high engine temperatures.
Racing water pump
The racing water pump provides for higher throughput in the charge air cooler water circuit, thereby reducing the charge air temperature considerably. This leads to an increase in power due to higher engine efficiency.
Performance pack 1
The Performance Pack 1 was especially developed for the KTM X-BOW. The pack includes lowering of the engine, an optimised drivetrain mounting and a catalytic converter with modified geometry. Lowering the engine by 19 mm lowers the vehicle’s centre of gravity. Furthermore, the torque stay is attached to the monocoque, thereby significantly reducing the effect of engine movement on handling. This makes the KTM X-BOW much smoother when changing positions of the accelerator pedal. The modified geometry requires a new catalytic converter.
Performance pack 2
The Performance Pack 2 contains a new air filter box and a chrome-molybdenum steel tubular space frame. This strengthens the rear subframe of the KTM X-BOW and increases the vehicle’s torsional stiffness considerably. The flow-optimised geometry of the carbon air filter housing increases throughput in the intake tract, thereby improving the responsiveness of the turbocharger. The new air intake system also generates a sportier intake sound.
Divert air-valve racing
The divert-air valve consists of an aluminum housing as well as a brass piston controlled by a spring-system. The advantage of the membrane caps used in the series models is a faster closing time following every gear change and an improved sealing especially in the high boost pressure range. These properties enable a more constant charge air pressure and improvement, therefore the level of efficiency of the turbo system.
Carbon intake flange
The carbon intake flange comes in combination with the Performance Pack 2 and includes an air-mass sensor.
The racing exhaust system, including 100-cell catalytic converter is FIA homologated and designed specifically for motorsport. It is 12 kg lighter than the standard exhaust system.
Racing catalytic converter
The racing catalytic converters are designed for motorsport purposes. They can be combined with all available KTM X-BOW exhaust systems.
