FUELING SPEED
Throttle Body Injection
Forget TPI, the 2025 KTM 2-stroke Enduro models feature electronically-controlled Throttle Body Injection - or TBI. The ECU, together with a new 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.
