2018 KTM 250 and 300 EXC TPI unveiled

That KTM's new 250 EXC TPI and 300 EXC TPI enduro bikes feature fuel injection wouldn't ordinarily be considered a unique selling point. However, because they're both powered by two-stroke engines, it most certainly is.

This unique innovation is called Transfer Port Injection. As well as reducing fuel consumption, the patented twin-injector system avoids the need to pre-mix fuel, thanks to a separate oil tank that supplies lubricant via an electric pump.

Apart from having different displacements, the 250 and 300 models are pretty much identical. Their specifications include a lateral balancer shaft to reduce engine vibrations, a WP nickel-plated exhaust pipe, a six-speed gearbox, a hydraulic clutch and an E-starter.

They're built around a chrome-molybdenum steel frame, which supports a cast aluminium swing-arm. The suspension set-up comprises a WP Xplor 48 upside-down fork with split-leg damping at the front, plus a WP Xplor PDS shock absorber at the rear. Braking is taken care of by wavy discs and Brembo calipers.

Deliveries are due to begin next month. In the UK, the 250 EXC TPI has a starting price of £7,349, while the 300 EXC TPI costs from £7,599.

Could TPI technology ever appear on a two-stroke street-legal motorcycle? Perhaps unlikely given ever-stricter emissions regulations, but maybe there's a possibility.
