Is KTM going to have fuel injection on the 2 strokes for 2013?

Now that all the four strokes are injected (I'm sure the SX 450 was a big project), will the 2 strokes be next?

While direct injection would be awesome, I would be happy with throttle body injection. It works great on snowmobiles, and is so much nicer then carbs.

Anyone see the Ossa in cycle world? Direct injection with the 2 stroke pipe under the seat! Looks like the perfect setup to me!

Check it out

I'm on an 09 450 XC-F now. Thought I would try a 4 stroke and don't really care for it much for my riding (mountain single track). Planning on going back to a 2 stroke (had a YZ and RM 250 previously). Hoping to see injection soon!

Probably not. Pretty likely for 2014.

I have a buddy that is just waiting for KTM to do this to get a bike. Seadoo did this in their 951cc two stroke twin cylinder engines and it worked great. It would be interesting to see KTM have this as an option.

F.I. should add a nice bump in horsepower. Until the 2nd year of production my 09' should do me fine.

So is it Because Seadoo or some other Co. has the patent on it and it is too expensive for KTM to do?
Here is a article I found, I do not know if it is factual or not.

I heard that they have it all ready to go, just waiting for a ($$$) reason to need to switch over, such as emissions related govt mandate from somewhere.

Maybe I should start writing my congressmen to introduce a law requiring all new 2 strokes to be F.I.?

Cuz I really want one.

Adding FI will not increase HP, but it will increase the complexity of a 2 stroke, increase the cost and increase the weight. It will also improve "ridability" as it will most likely be able to account for temp and elevation changes. One thing that the thumpers are just getting around to solving is the top end leaning out, that's why Kawasaki has a second injector on their 250f, so it's just matter of time before the rest of the 250f's (and 450's) get a second one.

The only advantage I see to having FI is that they will most likely have oil injection, so now you'll be able to top off at a gas station without the worry of mixing gas. And the "jetting" (fuel map) will be able to account for changing temps. I'm not too sure if that'll be worth the extra cost, weight, and complexity (did I mention that already?). In some ways I'm just not sold on EFI for dirt bikes. Partly because the fuel pump power wire fell off my old '08 RMZ450, which left me completely silent in the forest and with a 2 hour push back to the truck.

I would be interested if KTM did direct injection where you spray the oil at the crank, it mixes with the air and then the main injector is a direct injector in the cylinder. That would add quite a bit of complexity, but I think it would be the best method of dealing with fueling.

Meh, I'll stop riding 2 strokes when they go injected, no reason. All the fun of 2 strokes for me is the ol' simple mechanical and light-weight. Once you add the electronics, they might as well be a 4 stroke. Kool yes, still smokin' nope... :thumbsup:

I use to really be excited by the prospect of a DI 2 stroke but now I realize that I'm not interested in the4 cost and weight of the entire system.

I just want KTM to build a 350cc regular carbed 2 stroke in the new 250SX chassis. That is all that I need.

+1 on the 350cc carbed 2-stroke. I don't want the bike to gain 5 pounds, cost $1,000 more and require a degree in EE to work on. Keep that FI off of it.

Would a 350 be enough or maybe a 400cc?

You guys are way too worried about the FI.

Sleds and atvs have had it for a while and it works great.

You couldn't pay me enough money to go back to a carb'd sled.

Like I said, I don't care if its direct injection. Throttle body would be fine with me!

pretty much what im waiting for as well. fuel injection doesnt scare me the least bit, i work with it everyday. i really dont want to buy a carbed 250sx just to have the fuel injected model come out next year. carbs are easy, but so is fuel injection.

They already did that, the 380. Bring back the 380!! Oh my would I love to throw a leg over a 2013 380SX, yummy!!!

I really hope not. Would hate to see the added complication and weight.

Does anyone have a bore/stroke kit for a 300?? Not that the average guy needs one, but what the heck, the lastest chassis is sooo nice it could easily handle more power.

I would be a little sad if they came out next year because i bought a 2012 250 SX. I don't want it to be obsolete in one year. But it doesn't matter much because i rode my 04 yz125 from 2008 to 2012 and it was still somewhat competitive.

If it needs an electric fuel pump I say no thanks. Don't need fuel filters capacitors and relays on a simple easy to maintain to stroke. Jetting is childs play and easy to acomplish now why mess with it for little real world benifit.

Because as good as it is, the pain in the ass jetting is still the weak link to an almost perfect bike.
