2014 KTM 250 XC-F Base

2014 KTM 250 XC-F

The 250 XC-F has been is an established force. The feisty four-stroke 250 engine hits the scene with a new Supercross hampionship under its belt combined with cross-country competition in it's components. In fact, the 250 XC-F has taken Factory FMF/KTM rider Maria Forsberg to three consecutive Women's GNCC Championships and 2 X-Games Enduro X Gold Medals.

• CLUTCH

The highly compact CSS (coil spring steel) clutch uses a wear-free steel basket and eight clutch plates which are extremely heat resistant due to their steel carrier discs. The Brembo hydraulic system with its new master cylinder provides easy and precise modulation.

• CYLINDER HEAD

he centerpiece of the compact DOHC engine is its cutting-edge cylinder head with two overhead camshafts and DLC-coated followers – a design that allows to break the engine speed “sound barrier” of 14,000 rpm. Combined with extra lightweight titanium valves (intake 32.5mm, exhaust 26.5mm), flow optimized ports ensure a maximized flow rate for top performance.

• BALANCER SHAFT

In order to balance the mass-forces, the 250 engine uses a multifunctional counter balance shaft which also drives the water pump and timing chain. The engine receives a new water pump cover with a new gasket in order to optimize the seal.

• ENGINE MANAGEMENT SYSTEM (EMS)

In combination with the revolutionary injector position as developed by KTM, the Keihin Engine Management System with electronic fuel injection and 44mm throttle body provides the engine with a spontaneous response and maximum performance. For 2014, the wire harness of the 250 XC-F has been further simplified and even higher quality wires and connectors are used. In order to protect them against pressure washers, many connectors are now enclosed in new rubber boots. With an optional map-select switch from the PowerParts program, EMS continues to allow selecting different engine characteristics. In addition, 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.

• SUSPENSION/DAMPING

For 2014, all XC models are fitted with a newly developed 48mm 4CS Closed Cartridge fork featuring the patented 4-Chamber-System. The sophisticated design provides very constant and sensitive damping characteristics and an adjustable end progression. The new hand click adjuster system is now accessible on top of the fork, rebound on the right hand side, compression on the left. The fork is fitted with improved seal rings made by SKF and high performance fork oil (SAE 4). Compared to the predecessor, the new 4CS fork is lighter , easier to maintain and has been completely valved to match the shock for XC racing.

• SWINGARM

The cast aluminium swingarm has been developed with state-of-the-art calculation and simulation software and constructed, in terms of design and wall thickness, for minimum weight with optimum stiffness and precisely defined flexibility. For the 2014 model year, our engineers have revised the chainguide for the benefit of higher functional reliability, while simultaneously reducing the weight.

• AIR BOX

The airbox design offers maximum protection of the air filter against dirt while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM.

• FRAME

The state-of-the-art frame design made of lightweight, high-strength chromoly steel sections combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability.
