KICKSTART YOUR RACING CAREER

The KTM 125 SX is the most compact and lightweight of the full-size bikes and delivers a confidence-inspiring ride like no other. A lightweight chassis teams up with the most competitive 125 cc 2-stroke engine in its class, delivering superior agility and power to fulfil the demands of any young adrenaline 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.

ENGINE & EXHAUST

KTM 2-strokes have been tearing up MX tracks for decades and are undoubtedly the fastest on the track today. Thanks to years of ongoing development, these engines are the benchmark in performance and technology, with the perfect combination of power, weight and control. For 2020, small, but important refinements have been made, resulting in improved power delivery and reliability and through its melodic high-RPM screams, KTM 125 SX continues to deliver thrilling high-performance harmonics.

CHASSIS

To cater for the highly energized riding style of a 125 cc 2-stroke rider, KTM developed a chassis that delivers on their demanding expectations. The lightweight, high-tech steel frame is designed to respond instantly to rider input and provide accurate rider feedback. The flex characteristics help the bike to soak up those big hits while also delivering excellent agility and high-speed stability. For 2020, the suspension features improved damping characteristics. The reworked settings offer a slightly softer, more comfortable feel that, together with the frame, allows the rider to be 100% in charge of the ride.

ERGONOMICS & COMFORT

Momentum is crucial when laying down fast laps on a 125 cc. The ability to shift your weight quickly and easily to move in harmony with the motorcycle is key to maximizing flow. KTM 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 achieves 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 2020 KTM 125 SX gives the rider a definite sense of control and this is immediately confirmed the moment he hits the track.

BODYWORK & GRAPHICS

125 cc riders are renowned for riding with the most aggressive body language. Young, determined athletes riding with exaggerated style, pushing themselves and their machines to the limit. This was a critical consideration when developing the bodywork of the KTM 125 SX and was factored into the entire SX range. By using input from KTM factory riders, KTM R&D as well as Kiska Design, the 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.

SOFTWARE & ELECTRONICS

Absolute performance purity is the name of the game when it comes to the 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.
