Quote from Rob Twyerould, technical guy for KTM Australia, taken from the July issue of Australasian Dirt Bike:

"There is definitely a well-developed prototype at KTM, but they are waiting for the next round of emission restrictions to be announced before pushing forward.

"KTM has developed and patented it's own mechanical fuel pump system and a very compact oil delivery system to the bottom-end bearings, and the whole bike works really well.

"While there are some reasonable performance improvements, the real advantages of the system are in emissions and fuel economy. So the motivation for bringing to market will only come with the new emission targets."

Cool that they are still pursuing it, they will have my money whenever they release a SX model with it

It would be so sweet not having to jet you're smoker. I'd imagine it still has a reed valve system. Electronic power valve too.

Is it just me, or does it seem like KTM actually love building motorcycles?

Being that KTM is in the business of purely making motorcycles and related items, it is great to see a company evolve and adapt so quickly to our changing world (legal, ethical, noise, and so on).

I have never been a big KTM fan even after working at a dealer for two years. Its not that I dont like them, I just have always thought the Jap bikes are better.

Now more than ever it seems the Jap bike approach of making a model and milking it for years (plug Yamaha here) is becoming a huge disadvantage. I think KTM will have the best bikes very soon and that it wont even be a competition.

Thank you KTM for listening to your consumers and striving to always make a better bike. I am sure that I will eventually buy one. Right after I get off my 2011 Honda CRF450 that is 5lbs lighter than your 350.

So when can we expect these new 'emission restrictions' that they are waiting for?

In the video steedmills posted, it sounds like they are already pretty well advanced in the development of the fuel injected 2-stroke. They are talking about finding the right suppliers to supply the new pieces. I have no idea how much time this would take, but would that mean we could see them as early as 2013 or would that be too optimistic most likely?

Also, would it be more likely that they would give the 2-strokes EFI or DI? (not that I know the difference)

Direct Injection? Puhleeeze.....what fun is it owning a two stroke if you don't get to splash a little gas and oil on yourself once in a while?

J/K...Sounds awesome!

I wonder if this will have better emissions than a 4-stroke?

I have a Mercury OptiMax 90hp direct injection 2-smoke on my bay-boat and those things are incredible. Clean burn, incredible mileage, fires up first time, every time.

we in the north ride e-tech ski-doo's. our outboards are e-tech johnson/evinrudes. FI two strokes, oil injected....incredibly low emission. fast. why can't someone harness this tech for an MX bike?

this season I had a 2011 Ski Doo Summit Freeride with the 800 cc E-tec direct injection system, if KTM was able to "borrow" this system from their Austrian neighbours rotax I will be down at the dealership asap with my pre season deposit..

Because it's expensive and unnecessary. The beauty of the current 2-strokes is that they are simple and inexpensive. KTM engineers say that fuel injection is not a performance upgrade. It's an lower emissions upgrade. Why would you want to add cost to the bike for something that doesn't actually improve performance?

I owned a 2010 Summit P-tec(carbX2) and a 2011 Summit E=-ec(Di) the 2011 had 10 more hp and throttle response was insane,retail wise it was $ 1000 more(less than 10%), I could let the sled run indoors and it did not smoke out my garage,it used % 20 less fuel and 30% less oil, I ran it all season on 1 set of plugs, and it started first pull every time, even after being stuck upside down in a tree hole for 1hr. Think outside the box, and it will still cost less that a pOS four stroke that weighs more, makes less power per CC and is louder than my newborn baby......

Di does indeed perform better w/ a wider, almost 4 stroke like powerband.

Still, All I want is the modern carbed 250SX to have a factory built 350cc 2 stroke engine w/ a very wide powerband similiar to a modern 450F. Current technology will be fine.

It would be easy and cheap to build and the lower RPMs used would improve mpg as well.

Add $1000 to the bikes and they will sell like hot cakes...not.

It would still be about a grand less than a new valve muncher.

I understand your point CamP, and you are correct about it increasing the complexity and potentially the cost. The same can be said about linkages, cartridge forks, bladder shocks, liquid cooling, power valves, and even disk brakes.



I have to agree with Suns_PSD about what I'd like to see made- that sounds like one heck of a great bike.

The manufacturers sold less than 50k units of competition dirt bikes last year. That's down about 950,000 units from 30 years ago. Between the economy and the expensive technological bike developments, this sport is on it's death bed. Making the bikes more expensive is the last thing this sport needs.

What I don't understand is, every other thing in the world has an entry level, MX has a POS trail bike or top of the line race bike. Why don't these manufacturers have a decent MX entry level bike? 125cc 2 stroke with steel handelbars etc, that way the sticker shock doesn't scare off possible new riders

Why? Because the average motocrosser wants Dom Perignon Champagne but only has a beer budget. They say they want bikes with latest and greatest technological gizmos, then when they see the $9,000 price tags they don't buy them. This is a blue collar, red neck sport. We can't afford F1 technology.

What I'm talking about is, like with cars you have different trim levels. I can go get a brand new 20k work truck or I can get a 60k truck with all the bells and whistles. I just think that if the guys would sell a stripped down version of their race bikes, that people had the ability to upgrade as needed, you'll sell a ton more bikes total

The new 2013 Can Am MX250 will have a 250cc E-Tec Rotax engine. It will be the lightest bike made and have more power than a 450cc 4 stroke. It will have better fuel economy, therefore reducing the size of the tank and associated weight of the fuel. It will burn cleaner than any 2 stroke ever made. It will also be very quiet. It will have a completely different frame based off of current aircraft technology. All this, for $8999. Yes, it will be expensive, but Can -Am's like BMW and Mercedes, are not for everyone.

Haha, hell yeah to that 2 stroke rider.

"push those four strokes up boys"

Haha, awesome vid.

I have an 09 250sx, but I will not throw down on a new bike until the DI comes out.

I think DI will finally bring the 2 stroke to the top again.

When I'm trail riding here's some conss of my 2 stroke compared to my 4 stroke riding buddies:
-I don't trust it idiling very long, while my 4 stroke buddies let their bikes sit and idle all the time.
-Coasting down hills my bike loads up and fouls plugs if I don't pull in the clutch and blip the throttle.
-They burn noticibly less fuel.

From what I've read and watched vids about DI it sounds like it will fix these last few issues that hold the 2 stroke back from certain buyers.

I just hope it doesn't nueter the 2 stroke hit.

Both of the things you posted have to do with the same reason. Your bike is jetted wrong. A well jetted 2 stroke can idle fine. If you are fouling plugs, that is a sign. I NEVER foul plugs. Not bragging or anything, it's just the fact that if jetted correctly, it will not foul. It would do the same thing on a 4 stroke if jetted wrong.
