Has there been any talk of an injected motocross bike from KTM? I'm in the market for a 150 but I think I'm going to hold out if they are introducing their TPI technology to their SX lineup.

Was thinking it was rumored for the 2019 models? I think?

And there goes Jeffro. One of God's own prototypes. A super high-powered mutant of some kind never even considered for mass production. Too weird to live, and too rare to die.

That would be too much for 2-stroke fans.. TPI is working so much better than carb in enduro models that will get one for motocross also soon as they hit SX line. Some guys are already turning their TPI enduro bikes into MX just with harder suspension. There is not much left for Japanese factories if stuck with carbs.

That's what I'm asking. Is there any hard info regarding TPI on SX models? I am hoping 2019 simply because I see how awesome it would be and I have no interest in dealing with a carb.

KTM guys are not allowed to tell.. haven't seen any spy shots so its just about rumours.
250/300cc TPIs seems to work great for MX just with SX pipes and different exhaust port spring. That will
give you harder pull. Some have shaved head also to get more compression. So there should be no reason why
SX250 could not come with TPI other than higher price and R&D time to put aggressive maps out.

I don't see any reason why 125/150 could not work same way.
First talk was that Carb will make top end power but as we seen Dyno charts that hasn't been truth with 250/300cc TPI.

Just reading this makes me excited! I can see myself never buying another 4 stroke if this happens.

Next year may have more than one efi two stroke brand offering....

I already have my budget set for next year, and it includes a 300XC TPI....if it actually will be produced. The EXC's are ok. But, I want the SX chassis along with linkage and a good fork...

Tomac and/or Anderson for 2020.....

8 minutes in to this swedish podcast, Tomas (the host) talks to Justin Maxwell, Head of product marketing at Husqvarna. He claims they have no plans at this time to put the TPI on any TC or SX bikes.

Husky comes with linkage and new explr forks are good after little more damping added from stock.

Let me guess a Suzuki EFI 125....

Get the Husqvarna. They have a linkage and no PDS shock.

Well in reality there is 2 brands with fuel injection. KTM and Husqvarna, the differences between the EXC and the TE is pretty big. Big enough to actually look at them as completely different bikes.

I have a 2017 TE300. Not the TPI one but afaik they didn't change anything on the suspension and chassis between those years.
Comes with linkage and XPLOR forks. Suspension works great, especially the forks. I only adjusted the preload and the clickers.

I'll buy an efi-125 in a sec!! Having an always crisp 125 without the chance of it being to lean would be heaven! I loved my 2010 150sx and it was fairly easy to jet it ok (at least compared to the shitty Mikuni that they put in now). But it was a constant issue that wasalways in the back of my mind.

EFI is a good buzzword for 2t's for sure. The reality is it adds expense and complexity (we've been down this road with 4t's) and manufacturer's seem not anxious to roll it out if not forced to for closed course racing. Whether there is a performance improvement to go along with it is not a given. Don't misunderstand, I would want one too, I just don't expect they will change the world, and will probably be better after a few years of development.
