"Automatic Oil Injection System
The big news for the 2016 RR Enduro 2T models is the introduction of Beta’s electronic oil injection system on both the 250 and 300 RR models. This system was introduced in 2015 on the Xtrainer model and has proven to be a huge success among Beta owners. This new feature ensures a perfect fuel-oil mix under any conditions and engine speed while saving riders from having to pre-mix.
This new system also reduces 50% of the smoke from the exhaust compared to a traditional pre-mixed two stroke as the system is managed by an ECU with integrated mix and engine control which is able to measure the oil based on the engine’s revs and engine load measured by the TPS (Throttle Position System)."
Looks to me like the 2016 Beta 2-strokes are one step closer to a direct inject/fuel injection system. According to this the ECU manages the oil mixture along with a Throttle Position Sensor similar to an FI 4stroke, my guess is that pre-mix fuel is too thick to work through an injector so splitting the two would allow it to flow better. Whats your take on this?

Call me old fashioned but I like my two stroke smoking a little, and for all the complaining people do about mixing fuel it's remarkably easy to pour oil in a ratio rite and dump it in your gas. So easy, even a girl can do it.

Four strokes avoid this situation altogether. They're a dominant force in the market and also provide fuel injection systems which has alot of positive marketing buzz. I could see how Beta might feel that this technology may improve the marketability of a new two stroke design to both new riders and experienced four stroke riders they're trying to pull to the "dark side"
Following that logic, disc brakes are more 'complicated'
than drum brakes. Should we go back to drums?
It seems some people just dislike change.
You're still saying they're less complicated?
My grandfather had a 1970's 90cc yamaha that was street legal. It had a separate oil tank. I remember going around a turn when the motor locked up and sent me into a huge powerslide. Back at the garage we found the piece of belt or string that ran the pump had broken. That was one of my earliest "oh shit" moments.
The main advantage to direct injection is vastly improved fuel mileage, also the power is very smooth and linear. Not the same hit as carbs but more controlled and precise. I believe that all 2 strokes will be DI in the future in order to meet emissions requirements.

look at all they crap under the seat ill stick with a carby please
I can't wait for the first EFI KTM 2 stroke, it will be insanely interesting to see how it will compare to a carb 2 stroke.
I'v always rolled my eyes when i see people that glorify Yamaha for the 125 and 250 yet they have been releasing the same bike for 10 years and the price hasn't dropped. Don't get me wrong, the YZ 125 and 250 are great bikes but the fact is that they are charging a lot of money of a bike that is old, the YZ 125 and 250 is very cheap for Yamaha to build.
And the KTM bikes hasn't been that good but they have really stepped their game up these last years and the 2016 KTM 2 strokes are way better than the YZs.
Okey, i'm sorry i got a bit off topic but what ever.
Oil injection is awesome. The only reason pure race machines in any motorsport never used Oil Injection is because it takes a tad of HP to run the pump, even if it is driven direct off the crank.
Also, for warranty issues, it keeps retards from seizing shit. And if they run it dry, the dealer will know. It's a very easy tell tale.
That said, DI is ridiculous for a 2 stroke dirt bike, when a simple throttle body injection or case or transfer port injection is plenty good. And runs Far FAR less fuel pressure than DI. I run about 36 -38 PSI on mine.
