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.
