2013 KTM 150 SX
The KTM 150 SX comes with a set of upgrades for the year 2013. The changes include a new bodywork and significantly revamped suspensions.
In terms of suspension the old WP monoshock has been refined for the 2013 model and now features new settings which improve damping. Like the previous generation, the rebound and compression damping (high and low speed) can be easily adapted individually to the track and rider.
As far as ergonomy is concerned, the motorcycle is fitted with a comfortable saddle and a new Renthal Fatbar 827 handlebar. The new handlebar is offered in a black anodised finish and features a large Renthal crash pad.
The KTM 150 SX is propelled by a 1-cylinder 2-stroke engine, water-cooled, with reed intake and exhaust control. The power-plant is mated on a six speed transmission and has a 143.6 cc displacement.

Performance approaching that of a 250 with the handling of a 125. The perfect all-rounder in the 2-stroke segment appears even more aggressive now with new bodywork and significantly revamped suspension. You can’t go wrong here.
All SX models are equipped in 2013 with new Renthal Fatbar 827 handlebars, whose offset has been adapted to the needs of our motocross professionals (same as 996 Bend). As on the factory bikes, these handlebars are now black anodised and protect the rider with a large Renthal crash pad. Furthermore, we’ve also developed new grips that are manufactured in a 2-component process by Domino. Needless to say, four handlebar position settings are still the KTM standard.
Brakes from Brembo are standard equipment on KTM motocross bikes and, together with lightweight wave brake discs, they are recognised as the measure of all things in terms of application and brake performance. At the rear wheel, the brake calliper carriers have been adapted to the larger axle diameter on the KTM 150 SX 2013.
The modern frame design of lightweight, high strength, chrome-molybdenum steel section tubes guarantees an ideal mix of longitudinal and torsional stiffness, resulting not only in easy handling and precise steering behaviour, but also in excellent ride stability. The engine braces to the cylinder head have also been optimised, along with their attachment to the frame. The frames bear a new colour for the 2013 model year and they are still the benchmark in terms of weight and stability.
The WP monoshock has been further refined for the KTM 150 SX 2013 and, together with the KTM linkage system, it excels with its completely revamped settings for improved damping, more traction and even higher reserves against bottoming out. As ever, rebound and compression damping (high and low speed) can be adapted individually to the track and rider in no time at all.
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 sufficient flex. For the 2013 model year, engineers have redesigned the rear section of the swingarm to allow installation of a thicker rear wheel axle (25 mm instead of 20 mm) for the benefit of better tracking stability. Moreover, they have succeeded in reducing weight by more than 100 g by revising the bolts, cups and nuts on the linkage.
The tried and tested, integrated cooling system leads from the cylinder head through the frame triangle directly to the new radiators made by WP Radiator from tougher aluminium. Lack of piping simplifies radiator installation and improves air flow beneath the fuel tank of the KTM 150 SX 2013.
The revised design of the airbox guarantees optimum protection of the filter from dirt and maximum air flow for top performance. New, significantly stiffer intake snorkels (between filter and throttle body) also have a noticeable effect. New airbox covers are manufactured in a 2-component process with new in-mould graphics. The fixing for the left cover has been further improved, along with its installation. This makes quick replacement of the twin-air filter in a matter of seconds even easier. Needless to say, no tool is required - a feature that’s unique in the motocross world. Furthermore, an additional tab on the cover allows it to be secured with a bolt.
