Coming Soon? KTM Fuel Injected Two Stroke
It appears that KTM has Fuel Injection ready for two stroke motocross bikes. In the August 2008 issue of Motocross Digital magazine (free subscription available at http://www.motocrossdigital.com/ ) was the following blurb about the KTM effort.
The 250SX could have a bright future, it depends on what happens regarding the rules and regulations: KTM wants them to be introduced to MX2 to allow teams that don’t have millionaire budget to compete against the 4-strokes. For the 2-stroke, the injection is ready, and this would provide cleaner and precise power delivery.
While the idea of fuel injection for two-strokes has been talked about and discussed, there has been little to indicate that it would be workable on a racing two-stroke motocross bike. This news points to the fact that KTM has been working on it for quite some time and seems to have solved the issues that prevented fuel injection for racing two-strokes.
Since this article in Motocross Digital was written some changes have been announced in the FIM rules to allow two-strokes to compete with four-strokes in MX2 (250cc). There are also rumblings that this rule will be applied to the AMA Outdoor Nationals for 2009.
So there is a good chance the Fuel Injected 250SX KTM will be hitting the tracks in the very near future. This is great news for all the two stroke fans of the world.
Two thumbs up for the folks at KTM!

I may have to trade in the 05 rm 250 if KTM releases this bike next year.

That looks like a really sweet mechine
I can’t wait to see a test of it.

Why did KTM not go with Direct Injection as with 2 stroke outboard motors and a number of other makers? (Evinrude E-Tec type system – No fuel in the crank case at all)
This makes the 2 stroke the same or lighter on fuel than a 4 stroke – With no loss in power or torque!
Here are 2 interesting vids based on this

A nice clear explanation of Direct Injection.

I have rode a few bikes (Honda 85cc, Yamaha 85cc, and a KTM 125sx) And I absolutely love my KTM to a -T- the bike a great power and is the ONLY Bike Manufacturer to put a hydraulic clutch on there bikes. The bike has great top end and pulls like a BULL. Even though its a 2002 I still love it. I want the new KTM 150sx, I recommend this bike to anyone.

I am so glad I stumbled on this great web sight. I mentioned in a comment a few years back that fuel injecting a two stroke could be a viable answer to the excess unburnt hydro-carbons released in abondance by two strokes. I am just glad that this forum exists to get more people into trying to get two stokes back on the map. I can’t wait to see a DI 300cc two stroke outperform a 450 four stroke, or maybe even a 250cc could do the same. My friends say that riding a modern four strokes makes you lazy comparing the riding technique needed to make a two stroke go fast. One must be really fast and efficient in the gear shifting department.
