First Look at the 2018 KTM 250XC-W TPI


Even though KTM only introduced a brand new EXC generation in 2017, the challenges never stop. This means research and development also never cease at the Austrian headquarters, and so in 2018, KTM is once again set to deliver the next revolutionary game-changer in competition offroad sports: the world’s first 2-stroke, offroad competition bikes with serial, electronic fuel injection.

Combining top performance and outstanding rideability, the KTM EXC TPI models with 250 and 300 cc of displacement will be distinguished by the lowest weight in their class, intuitive handling and a unique style, along with the awesome READY TO RACE performance expected of any genuine KTM race bike.

“TPI” stands for “transfer port injection”, and the groundbreaking new 2-stroke represents another major step forward on a global scale, once again demonstrating KTM’s unrelenting and continuous commitment to 2-stroke technology as such. The benefits to owners are clear: besides huge improvements in fuel efficiency and clean exhaust emissions, the electronics do away with the need for rejetting, no matter the elevation of the race venue, prevailing weather conditions and the like. Also, engine lubrication on the TPI models is automatic from a separate oil tank and electronically controlled oil pump, obviating the use of pre-mixed fuel-oil mixture.

In short: TPI means a new dimension of READY TO RACE DNA in every detail. And more than that: TPI is the living proof that KTM’s ongoing commitment to offroad racing in general will never stop, and its dedication to 2-stroke technology in particular is alive and well. In fact, the state of the art R&D department in Mattighofen is expanding, while the new motorsport division demonstrates KTM’s growth and continuing investment.

The new KTM 250 and 300 cc Enduro models fitted with the revolutionary TPI serial fuel injection are high-end, READY TO RACE products, which set new standards in the 2-stroke segment. TPI stands for „transfer port injection”; a global-first, groundbreaking technology for 2-stroke racing engines that delivers a previously unattainable combination of top performance and outstanding rideability. Lubrication is taken care of by an automatic system with a separate oil tank and electronically controlled oil pump instead of using premix.

In addition, the TPI bikes benefit from the complete set of KTM Enduro racing features such as an E-starter powered by super-lightweight lithium ion batteries, sublime Brembo brakes, self-adjusting hydraulic clutches, KTM ‘No Dirt’ footpegs and gear shift levers, KTM toolless air filter boxes, quick- release fuel lines, polished hubs, WP Xplor 48 split forks, WP Xplor PDS shock absorbers and of course typical KTM precision-welded chromoly frames. This means they are not only among the lightest bikes in their respective classes, but they also deliver intuitive handling, while the exclusive bodywork sets them apart with a unique style. For 2018, Canada and the USA will only be offered the 250 model of the EXC TPI.
