🎥 TPI Misconceptions, Part 1: Throttle Characteristics
In 2017, KTM first released their fuel-injected two-strokes: the 2018-model 250 and 300EXC TPI. Featuring KTM’s patented Transfer Port Injection (TPI) technology, these models offered massive advantages – such as automatic compensation for altitude and temperature, better fuel economy, reduced emissions, ease of starting, smooth idling and improved rideability. And the 300EXC TPI soon took over as KTM’s biggest-selling model in several markets around the world, Australia included.
But, as is the case with any new technology, there have been some teething problems with the TPI – some of them inherent in the TPI technology itself, some of them a result of riders not yet adapting to, or understanding, the idiosyncrasies of a TPI engine.
So to help owners properly understand the characteristics of their TPI machines, we’ve put together a five-part series of short videos with KTM’s Technical Services Manager, Rob Twyerould, to deal with the more widespread misconceptions about TPI, and to explain how the TPI system on KTM’s 2020 models has been refined.
In part 1 of the series we delve into the throttle characteristics of a TPI machine.
