KTM have officially launched their range of 2-stroke fuel injected enduro bikes in Eisenerz, Austria: the KTM 250 EXC TPI and KTM 300 EXC TPI.
The KTM 250 EXC TPI and KTM 300 EXC TPI machines (EU models) are fitted with a newly developed TPI fuel injection system.
The patented EFI system, with two injectors into the transfer ports of the cylinder, makes for a smoother engine, with a hefty reduction in fuel consumption. There's also no need to pre-mix fuel, or change the jetting for different environments.
With the upgrade comes a new throttle body, and a new EMS (Engine Management System), which includes a new ECU (Electronic Control Unit) that makes use of a number of sensor readings to get the best possible ignition timing and fuel injection.
Additionally there's a new cylinder, air filter box, oil pump and fuel tank for the fuel injection application, a new high-tech chromoly steel frame; adapted to home the oil filler cap and hose to the oil tank within the frame tube, plus brand new graphics for MY2018.
“It is a very proud moment for us to unveil the world’s first serial electronic fuel injection 2-stroke offroad competition bikes. We at KTM are committed to developing revolutionary technology, and with the KTM 250 EXC TPI and KTM 300 EXC TPI models we feel the game has once again been changed, as this is a global first. Our goal was to create a 2-stroke Enduro bike that would not be incredibly complex, while also retaining the feel of a carbureted machine, yet with all the benefits of fuel injection. This includes the elimination of the need to pre-mix fuel or change the jetting for different environments, which is a major benefit to the rider for hassle free, 2-stroke fun,” said Joachim Sauer, Product Marketing Offroad.
