The hydro-formed, laser-cut, and robot-welded frame has undergone major updates to improve overall dynamics, anti-squat behavior, and overall stability.
Designed and constructed with specifically calculated parameters of longitudinal and torsional flex, the new frame provides exceptional rider feedback, energy absorption, and straight-line stability. This is thanks in part to repositioned rotating masses in the frame and the forged steering head connection, together with an all-new shock mount, which is no longer connected to the main frame tube.
Thicker frame walls also contribute to improved reliability and specific rigidity in high-stress areas such as the steering head and the shock mounts, while new parallel frame mounts across the 2023 2-stroke range improve flex characteristics.
An important highlight of the new frame is repositioned footrest mounts. These have moved inwards, making them less susceptible to hooking in deep ruts or when scrubbing jumps. However, the overall size of the footrests has increased by 26%, designed with the help of state-of-the-art finite element analysis (FEA) which uses a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. This has resulted in dramatically improved comfort and control when standing on the pegs.
The frame of the 2023 KTM SX and SX-F models is finished in black powder coating and a hard-wearing matte surface. Additionally, black frame protectors featuring a new and improved grip texture, guaranteeing superior protection, durability, and ultimate grip are fitted as standard.
