The new KTM 125 SX is the most compact and lightweight of the full-size bikes and delivers a confidence-inspiring ride like no other. A new lightweight chassis teams up with the most competitive 125cc 2-stroke engine to date, delivering superior agility and power to fulfil the demands of any young adrenalin seeker. This 2-stroke screamer is the ultimate entry point into the pro ranks and a sure-fire way to add to the trophy collection.
The latest version of the 125 SX engine is once again the most competitive and powerful engine in its class. With an outstanding power-to-weight ratio, low cost and overall simplicity, it is clear that 2-strokes will continue to have a successful future at KTM. The compact and durable 17.2 kg engine was developed using the latest KTM engineering know-how, resulting in broad power across the rev range. Its easy rideability and outstanding performance are benefits that equate to faster lap times and better results.
To heighten the highly energized riding experience of a 125cc 2-stroke, KTM developed a new chassis that is light and responsive enough to enhance its dynamic reputation. For 2019, the KTM 125 SX features a new lightweight, high-tech steel frame that not only responds accurately to rider input, but has also been optimized for better rider feedback. The new flex characteristics help the bike to soak up those big hits while also delivering excellent agility and high-speed stability. As a whole, this new chassis allows the rider to be 100% in charge of the ride.
Momentum is crucial when laying down fast laps on a 125cc. The ability to shift your weight quickly and easily to work in perfect harmony with the motorcycle is key to maximizing flow. KTM has focused extensively on the optimal ergonomics for high-level performance, ensuring a riding position that offers the best control and, with the option of several handlebar positions, can be adjusted to suit every rider and condition. The way a rider interacts with the bodywork, seat, footpegs and handlebars, results in maximum balance and control. For this reason, no compromises were made in these important areas and only the best quality products and designs were used. Sitting on the 2019 KTM 125 SX gives the rider a definite sense of control and this is immediately confirmed the moment he hits the track.
125 cc riders are renowned for riding with the most aggressive body language. Young, determined athletes riding with exuberant style and pushing themselves and their machines to the limit. This critical consideration went into the development of the bodywork of the KTM 125 SX and was factored into the entire 2019 SX range. By using input from KTM factory riders, KTM R&D as well as Kiska Design, the new bodywork of the KTM 125 SX achieves complete harmony between rider and bike. The main goal was to provide the perfect contact points for the rider, allowing him to move as freely as his spirit demands, with the control to match his intentions. The bodywork is full of intelligent design elements, like the I-beam structure on the front and rear fenders, which guarantee maximum stability with the lowest possible weight. The new modern design and graphics portray an impressively fast and aggressive look that sends a clear message to the competition.
Absolute performance purity is the name of the game when it comes to electronics and the new KTM 125 SX. Undiluted 2-stroke simplicity, with an hour meter to keep a check on how long you've been shredding and an optional rev counter to assist with perfect setup.
