When it comes to motocross bikes, KTM offers a full breadth of some of the most powerful bikes on the market, including the spectacular KTM 450 SX-F.
The 450 SX-F’s high-quality chassis allows advanced riders to convert the brutal power of the brand’s innovative DOHC four-stroke engine into controllable traction, even on the toughest MX tracks. Add that to a newly-developed clutch and a robust steel cage, and you have a motocross bike that’s truly the class of the field. Especially when you throw in the transmission-friendly back-damping that makes use of a spring washer for the first time instead of the customary conical springs, substantially reducing the operating force.
Adding to the bike’s unbridled versatility and all-around functionality is a new technology for the exhaust. In conjunction with the innovative HPRS (Header Pipe Resonator System) and large-diameter silencer, the 450 SX-F’s super-light titanium exhaust manifold ensures plenty of power at low noise levels.
In terms of its design, the 450 SX-F was built to compete, featuring a state-of-the-art frame that’s made from high-quality chrome-molybdenum steel. The bike’s bodywork is extremely slim, making for a dynamic ride that’s characterized by a particularly balanced geometry that combines easy handling with razor-sharp precision.
Handling and ride ability are always chief requirements for world-class motocross riders. On both those fronts, the KTM 450 SX-F is in a true class of its own, making it an ideal choice for riders looking to make a name for themselves in the motocross world.

DDB&Co Istanbul was commissioned by KTM Turkey with the making of a print ad that ended up bringing an award for the original idea. The ad is for their 250SX motorcycle, a veritable off-roader, so the rider’s behavior is almost justified.
Congratulations KTM for this ad, which reminds us of Aprilia’s…
Most of KTM’s dirt bike fans have started on this bike or at least heard that it’s the best thing – built by the Austrian manufacturer – to start on if planning to hit the motocross tracks and even compete in a few races after gaining enough experience. Not to be compared with any of the 125 cc four-strokes is the 2009 KTM 105 SX, a machine that is light, maneuverable and which benefits of the all-important two-stroke engine performance to call it a blast around the track. Yes, it’s a 105 cc; you can start getting over it now…or get on riding.
In a dirt bike world now dominated by four-strokes, KTM not only adapts perfectly, but also offers a sweet remember of where it all began in the form of the 2009 KTM 125 SX. Highly competitive, this bike is all about lightness, chassis corner carving abilities and loads of torque obtained from a small in displacement and big in attitude two-stroke motor.
2009 sees the introduction of the all-new KTM 150 SX, apparently a "new" two-stroke dirt bike, but in fact an upgraded and renamed 144 SX. Like its inspiration model, the 150 SX brings the best of the 125 cc and 250 cc worlds in an incomparable product characterized by extreme ease of handling and serious two-stroke power to work with. It stands as the choice of middle, an uncompromising one, for dirt riders who know exactly what they request from a bike.
Some might say that two-stroke dirt bikes are dead and buried, but KTM says “Not Yet!” to that and offers a great model to back up their affirmation – the 2009 KTM 250 SX. This bike is keen on providing the demanding two-stroke crowd with loads of torque, defining a unique powerband as well as sound and smell, all contributing to the unmistakable riding experience.
KTM is keen on delivering the best of every product so, for that reason, they dig deeper in each of their bike’s possibility sack in order to find what can be improved, upgraded or simply lightened in an attempt to set each bike apart from its competitors. The 2009 KTM 250 SX-F is a very good example of what the Austrians can achieve with a quarter-liter engine and a race-derived chassis so it’s well worth checking out also because KTM claims it can even do better than two-stroke bikes in certain areas.
KTM worked their magic on the biggest 2009 SX-F model, the MX1-destined 450 and, like on all other racing bikes, it all stands in the details. The retuned engine is claimed to provide a healthier rush across the powerband while chassis and controls updates are aimed at improving handling as the rider is supposed to feel more at home on the new model than on the previous one.
Leaders of the MX1 and MX3 classes, the KTM 450 SX-F and KTM 505 SX-F feature the latest technology concerning both engine and frame which makes winning a sweet confirmation of the already expected results. The light electric starter only makes the rider’s life easier when things don’t go as expected.
KTM plans one winning the World Championship with a totally revised 250 SX-F, a motorcycle relying on its great 250cc four-stroke engine that delivers its power all the way from low to the end of the rpm range. Fitted on an ultra-light and versatile chassis, that engine couldn’t have found a better place. Shall I even mention that the 2008 250 SX-F features a new appearance? Ok, it does!
Filled with power and agility, the KTM 250 SX is most likely to dominate the MX1 charts and so make a name of itself with the help of a super light and stable frame on which a quarter liter two-stroke engine is being fitted. The suspensions received new settings, but you shouldn’t worry about the maintenance as it is as low-cost as possible.
The tract is its middle name as it was born there and it is also where it likes to spend most of its time. The 2008 KTM 144 SX is small, agile, a real powerhorse from KTM, and manages to effectively deliver its power to the rear wheel and blow away the competition.
