2014 KTM 500 XC-W Base

2014 KTM 500 XC-W

The 500 XC-W is one of the most powerful enduro machines of its class. Combining low weight and high displacement, high-tech SOHC 4-stroke technology is the right choice for all who are looking for maximum performance, combined with playful handling.

• ENGINE

Developed for tough enduro racing, the SOHC engine with 510.4cc is distinguished by an extremely compact design, easy maintenance and an excellent durability at a minimal weight. Together with the Keihin EFI system, they provide unrivaled enduro specific performance and rideability.

• COUNTER BALANCER

In order to balance the mass-forces, the engine uses a counter balance shaft which doubles as a water pump drive.

• ENGINE MANAGEMENT SYSTEM (EMS)

The Engine Management System (EMS) by Keihin with electronic fuel injection and 42mm throttle body ensures a spontaneous response and maximum engine performance. An oil-cooled 196 W AC alternator provides sufficient energy for the fuel injection, lighting and other electrical loads. With an optional map-select switch from the KTM PowerParts program, EMS allows selecting different engine characteristics. In additon, the optional User-Setting Tool allows to readout engine data with a laptop and change the ignition and injection mappings with a few mouse clicks.

• DDS CLUTCH

Optimized for 2014, the single-piece basket of the DDS (Damped Diaphragm Steel) clutch is machined from solid high-tensile steel in one piece together with the primary drive gear. This process guarantees unbeatable reliability and contributes to the narrow engine width due to its compact rivet-less design. Additionally, this construction allows the use of thin steel linings which also contribute to the compact clutch dimensions. The diaphragm spring makes it possible to implement an additional rubber damping system inside the clutch hub, guaranteeing reliability for the transmission and good traction. In addition, a stronger inner hub further increases stability. Finally, the hydraulic clutch mechanism by Brembo in conjunction with the diaphragm spring guarantees a very light operation and good controllable modulation of the clutch.

• CYLINDER HEAD

The cylinder head is equipped with a single overhead camshaft which has been lightened by 10 percent for 2014. It activates two titanium intake valves and two steel exhaust valves. The weight optimized valve train leads to lower friction for improved performance as well as less engine braking action. Also, an optimized cylinder head gasket now guarantees increased durability in extreme conditions. The automatic decompression mechanism has also been strengthened to further optimize durability.

• CRANKSHAFT

The crankshaft with a stroke of 72.0 mm and ultra-lightweight con rods are made by Pankl from special, high-tensile strength steel. They have a plain bearing in the big end. The previous needle bearing is replaced with two force-fitted XCF-W shells that run directly on the crank pin. This design enhances the engine's durability, allowing to lengthen the crankshaft service interval.

• SUSPENSION/DAMPING

The first rate WP Suspension elements have been further improved for 2014. Specially designed for enduro riding and in some models with an optimized tuning, they ensure maximum traction and plenty of comfort. Of course, compression and rebound damping can be adjusted to the track conditions and the rider's preferences with a twist of the wrist - the rear monoshock has separate high and low speed adjustments.
