KTM unveils new two-stroke fuel injection engine

Even though a two-stroke single-cylinder engine gives the best power-to-engine weight ratio, its biggest drawback is the poor emissions control inherent in the engine’s design. Austrian maker of dirt-bikes and other performance motorcycles, KTM, has unveiled a new two-stroke single that it believes will revolutionise the off-road motorcycle world.

Designed to fit into its 2018 enduro bike, the KTM EXC, the two-stroke, single-cylinder engine – developed in-house at KTM’s Mattighofen R & D facility – will feature a new way of delivering fuel and lubricant to the cylinder. Dubbed Transfer Port Injection (TPI), KTM claims this new technology drastically reduces fuel consumption while eliminating the need for pre-mix fuel or adjusting carburettor jetting.

“This is an incredibly exciting development for KTM. We have been developing 2-stroke fuel injection for some time, and our goal was to create competitive motorcycles with all the benefits of fuel injection,” said Joachim Sauer, KTM Product Marketing Manager. The off-road bikes that will receive the new two-stroke TPI engine are the 2018 KTM 250 EXC TPI and KTM 300 EXC TPI, which debut in May.

“In the USA and Canada, the new 2018 KTM 250 XC-W TPI will be available in very limited quantities in late fall,” said Sauer. For Malaysia, the 2017 KTM motocross range starts with the two-stroke 250 EXC Six Days, which retails for RM38,160.

Next up are the four-stroke enduro 250 EXC-F and 250 EXC-F Six Days, which go for RM41,870 and RM45,050, respectively. The KTM 350 EXC-F and 350 EXC-F Six Days are priced at RM42,400 and RM45,580, while the 450 EXC-F at RM42,930 and the 450 EXC-F Six Days at RM46,110 top out the range.

Also offered is the competition-only KTM 450 SX-F – which omits lighting and other road legal equipment – at RM39,750. All prices include GST.

    Rm40k for a bike? Prices should come down. Too expensive for most Malaysians.

    Dear Mohan, is there a typo error in the article ?!

    It says the 250 EXC-F & 250 EXC-F 6-Days is priced at RM41,870 & RM45,050 .

    The KTM 350 EXC-F & 350 EXC-F 6-Days are priced at RM42,400 & RM45,580

    The price difference is only RM530 for KTM 350 compare to the KTM 250. Thanks for the article.

      These are the official prices from KTM Malaysia as at September 2016.

      It should be remembered that these are essentially racing motorcycles. They are meant for different racing classes, hence the difference in capacity, but not necessarily in price. The only real difference between them is the engine stroke and bore.

    2 stroke engine. Pick-up way faster than the 4 stroke bike. I still remember my Suzuki TS 185 bike which i used in the 80’s.
