2013 KTM 350 XCF

Posted on by  

The KTM 350 XCF has received a set of improvements for 2013. The most important one is the revamped engine which is now significantly lighter than the previous unit. The lighter engine weight has been achieved thanks to the new die cast housing. The new engine is also fitted with a new Electronic Fuel Injection system and is brought to life by an electric starter.

You also get a modern frame made of lightweight, high-strength, chromoly steel section tubes. This advanced frame design offers a great combination of longitudinal and torsional stiffness, which is directly translated into a sharp handling and great stability. For the bike’s great stability we also need to give credit to the advanced WP Suspension system which includes a front Up Side Down 4860 MXMA CC fork paired with a rear 5018 BAVP DCC shock absorber.

This unique bike supplies the power and performance of a 450 combined with the handling of a 250. For 2013, the 350 xc-f engine has been scrutinized for power and performance, a completely new chassis and new bodywork for a new generation of xc.

Revamped engine


The advantage of the ktm 350 xc-f has always been its weight. And now the bike’s heart is even lighter. Another 500 g (17.64 oz) and more have been lost thanks to the new die-cast housing. The extremely short-stroked dohc power unit, equipped with the latest generation of efi, excels with its even wider rev range and exceedingly efficient rideability. And, just like all ktm four-strokes, it can be activated with an electric starter.

Cylinder head


The modifications to the 350 cm³ (21.36 cu in) dohc engine can be summarized very easily: more power at less weight. Flow-optimized ducts supply greater gas flow and better cylinder charging. Strengthened valve heads and valve seats plus valve springs with a higher spring force make it possible for the lightweight titanium valves to withstand the increase in maximum engine speed from 13,000 rpm to 13,400 rpm. Or more simply said: more power for the new 2013 ktm 350 xc-f.



Factory bike or production bike? The crankshaft on the new 2013 ktm 350 xc-f is equipped with a revolutionary plain bearing in the lower conrod eye. In conjunction with the stiffened crankshaft and a lighter piston, this design is a key prerequisite for increasing the maximum engine speed to 13,400 rpm and the impressive peak performance of the 350 cm³ (21.36 cu in) engine. But not everything revolves around pure power. One major benefit is an extension to the service intervals for the crankshaft; a benefit in terms of time and costs.



The modern frame design of lightweight, high-strength, chromoly steel section tubes guarantees an ideal mix of longitudinal and torsional stiffness, resulting not only in easy handling and precise steering behavior, but also in excellent ride stability. The four-stroke frames impress in my 2013 with a stiffening of the frame triangle and thinner-walled down tubes. This leads to an improvement in tracking stability (increased torsional stiffness) accompanied by a reduction in weight. The engine braces to the cylinder head have also been optimized, along with their attachment to the frame. The frame bears a new color on the 2013 ktm 350 xc-f and it is still the benchmark in terms of weight and stability.

Telescopic fork


The further improved 48 mm (1.89 in) upside-down fork featuring closed-cartridge technology has been optimized with completely revamped xc settings made specifically for the united states market for perfect harmony with the new frame and engine. The new oil is significantly more wear-resistant and guarantees more consistent damping throughout both the course of a race and the bike’s life cycle. A new lower triple clamp is 80 g (2.82 oz) lighter and, just like the upper triple clamp, cnc-machined from high-quality aluminum, whereby the steering characteristics, and hence, the responsiveness of the fork have been noticeably improved.



The cast aluminum 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 sufficient flex. For the 2013 ktm 350 xc-f, engineers have redesigned the rear section of the swingarm to allow installation of a larger rear wheel axle (25 mm (0.98 in) instead of 20 mm (0.79 in)) for the benefit of better tracking stability. Moreover, they have succeeded in reducing weight by more than 100 g (3.53 oz) by revising the bolts, cups and nuts on the linkage.



The wheels are fitted with lightweight, cnc-machined hubs and high-end giant rims, plus new, black-coated spokes with aluminum nipples, guaranteeing the highest levels of stability while keeping weight to a minimum. The dunlop geomax mx51 tires stand for excellent traction and performance. For the benefit of greater ride stability on the ktm 2103 350 xc-f, the rear axle has been increased in diameter from 20 mm (0.79 in) to 25 mm (0.98 in).



Brakes from brembo® are standard equipment on ktm xc bikes and, together with lightweight galpher wave-type brake discs, they are recognized as the measure of all things in terms of application and brake performance. At the rear wheel, the brake caliper carriers have been adapted to the larger axle diameter for my 2013.
