​The ​2025 KTM ​2-stroke ​Enduro models ​feature​ electronically​-controlled Throttle Body Injection​ – or TBI. The ECU​​, together with ​a Keihin​ ​39mm throttle body​,​calculates​ the ​ideal air-fuel mixture by constantly analyzing water temperature, air temperature, ambient pressure, ​and ​pressure within the crankcase, ​the ​rpm, and the throttle position​ to ensure the smoothest and most consistent power delivery​ in the most gnarly of ​enduro conditions.

Specifically engineered for longitudinal rigidity, the 2025 KTM 300 EXC HARDENDURO is engineered around a gloss-orange powder-coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This is achieved by repositioning the rotating masses in the frame along with a forged steering head connection. The footrest mounts also feature a slim design for less risk of hooking up. And when the ride comes to an end, a forged one-piece side stand ensures your enduro weapon stands proud.

The 2025 KTM 300 EXC HARDENDURO is hard to miss, with striking white-on-black graphics, and a ribbed black seat cover all overlayed onto black and orange fenders, it makes a statement. This is one graphics package you won’t want to swap out.
