FEATURES

  • FASTER SHIFTING: The 2025 model benefits from a revised transmission shaft and shift drum that work together to deliver noticeably quicker and more precise gear changes — especially under heavy load or during high-RPM conditions. This means smoother power delivery and improved rider control when it matters most.
  • OPTIMIZED CHASSIS FLEX: KTM engineers reworked the engine mounts and updated the polyamide-reinforced subframe to fine-tune the bike’s flex characteristics. The result is more predictable cornering, increased rider feedback, and a planted feel when attacking rough or rutted terrain.
  • SHARPER STARTS: A factory-installed WP FACTORY START DEVICE ensures aggressive launches right off the gate. It locks the front suspension down to reduce front-end lift and maximize traction, giving you the edge during holeshots and tight first corners.
  • MORE GROUND CLEARANCE: Thanks to a newly designed flatter undercarriage and integrated skid plate, the 450 SX-F gains valuable ground clearance. This gives riders more freedom when choosing aggressive lines through deep ruts, whoops, or off-camber sections.
  • READY TO CONNECT: With the optional Offroad Control Unit and the KTMConnect app, riders can access real-time engine tuning, traction control settings, and ride modes through their smartphone. This gives weekend warriors and race teams alike a new level of control and customization.
  • LAUNCH & TRACTION TECH: Standard features like Launch Control, Traction Control, and a Quickshifter system come preloaded for the 2025 model. These electronic aids work seamlessly together to optimize starts, prevent wheelspin, and maintain momentum across varied terrain.
  • CENTRALIZED MASS: Every component — from the engine to the electronics — has been carefully positioned to lower the center of gravity and centralize mass. The benefit? Improved balance, stability, and less rider fatigue during intense motos.
  • MOTO-PROVEN ERGONOMICS: Updated plastics and bodywork feature reshaped shrouds and contact points that provide better rider grip and control. Whether standing or seated, the bike feels narrower and more agile, helping you shift body weight efficiently during aggressive cornering or jumps.
  • DURABILITY-FOCUSED DESIGN: Built to take a beating, the 2025 KTM 450 SX-F incorporates upgraded frame reinforcement, tougher plastics, and a hybrid aluminum/polyamide subframe. This ensures long-term durability without sacrificing the lightweight feel KTM is known for.
