We simply completed our first day of using the fuel-injected 2018 Husqvarna TE250i two-stroke. The world press introduction was held on the Panorama Ski Resort in British Colombia, Canada, which had simply hosted a hare scrambles earlier within the month. The bike is similar to the KTM 250XC-W TPI that we rode a month in the past, however it has all the standard chassis variations that differentiate Husky and KTM. The rear suspension has linkage, the airbox is unified with the subframe and there are a selection of element variations. Of these, essentially the most vital for 2018 is that Husqvarna is utilizing Magura brakes, moderately than Brembos.

The star of the present continues to be the gasoline injection system. After experimenting with throttle-body injectors, resembling these utilized by four-strokes, and with direct injection as we’ve seen within the marine and snowmobile trade, the engineers in Austria settled on inserting the injectors instantly within the switch ports. A Del Orto throttle physique meters clear air into the engine and oil is injected because it enters the crankcase. It isn’t till the cost is transferring from the crankcase to the combustion chamber that it’s blended with gasoline. The engineers say this isn’t fairly as clear as direct injection, however it doesn’t require huge gasoline strain and extra complication. The principle purpose of all this was to fulfill Euro four and 5 emission necessities. The U.S. necessities for off-road and dual-sport emissions are totally different, and the engineers says that’s a purpose for an additional day.  For now, it’s a closed-course competitors off-road bike within the U.S., simply as all two-stroke bikes are.

A by-product is superb efficiency at altitude and a easy energy supply. At Panorama, the bottom of operations was 3000 or 4000 ft, however the path took us as much as nearly 8000 ft. That may be a jetting nightmare with any conventional two-stroke. With the 250i, the one change was a lower in horsepower. The bike nonetheless began simply and ran cleanly at altitude. There have been some conditions that would confuse the bike’s processor; in case you held the throttle large open, then chopped it, then bought again on the fuel, it will cough and take a second to regain its composure, however it will nonetheless recuperate and clear itself up shortly. On the different finish of the dimensions, when the throttle was simply barely cracked open, the efficiency was excellent–even higher than essentially the most completely jetted “regular” two-stroke. The bike chilly idle all the way down to a crawl and irrespective of how jerky you have been with the throttle, it wouldn’t miss, bathroom or stall.

In outright efficiency, it’s unattainable to say how this bike would evaluate to the present carbureted TE250. As we mentioned, even the bottom level of our experience was excessive sufficient to have an effect on efficiency, and we didn’t have a normal bike for direct comparability. Nonetheless, it’s secure to say that the ability supply is way more linear. The usual 250 has a definite hit, even at altitude. The EFI is bike so easy that it feels considerably sleepy.

There are a couple of different issues to know in regards to the 250i. Two maps can be found by way of a handlebar-mounted swap, however past that, the map is fastened. There are not any EFI tuning instruments that Husqvarna will make out there to the buyer, not but, anyway. Beginning is at all times simple with the button or with the kickstart lever, and there was by no means a necessity for the “choke” which is only a quick idle. If the battery is low, the kickstarter is perhaps a good suggestion, but when the battery is totally lifeless, all of the kicking on the earth gained’t work. The battery is an integral a part of the system. Gasoline financial system is meant to be about 40% higher than a normal two-stroke, and it barely appears to make use of oil in any respect. The gasoline tank is analogous in quantity to the usual tank, however it homes a fuel-pump which makes use of up a little bit area. The bike ought to be a few kilos heavier.


If U.S. riders are nonetheless a little bit reluctant to embrace the brand new order, that’s comprehensible. Keep in mind, it’s not about us. This bike was developed for the European market, the place will probably be street-legal. In consequence, Europe is getting most of them. There will likely be only a few of the EFI 250s imported to the U.S. and never a single TE300i. We will likely be getting the usual 250 and 300, full with a rejetted Mikuni carburetors and all of the chassis updates. Costs haven’t but been set.
