It seems like a no brainer to me: - Lugs at even lower revs than carb, harder to stall, should be easier to find traction and feather throttle - Works at all altitudes without adjustment - According to MaverickDH's comment on here it DOUBLES the life of the bottom end (no fuel diluting the lubrication), and gives 200hours life on the top end due to better fuel combustion - no more mixing oil and fuel. Combined with lower servicing this significantly changes the ratio of time spent in the saddle vs time spend on the end of a spanner. - Better fuel economy. EDIT think about how that leaves electric bikes further behind... "electric bikes are better, they just need better economy but they are getting there!"... yeah, well now you have 30% further to go hahaha
@@elijah1923 well newer ones are pretty light, have fast charging. Weight isn't always in battery some electric bikes and cars can be lighter than gas counterpart.
Note 1; No one in Europe is riding their TPi restricted. The carb ones was also restricted and it was removed at the dealers. 2; Cold/warm weather climate. No need to "re-jet". 2; People mentioning "more things to go wrong!". Where have you guys been when 4-strokes got efi? I rarely see any problem with them at all and I never had any problems with them.
pelleper 4 strokes have oil inside them. When your oil injection fails on a two stroke you got probably 5 mins to shut it off before it blows. You shouldn’t really have to rejet your bike because usually you ride during the same season. And if you do have to re jet that take 10 mins. Adding electronics to a motor is just over complicating it. It’s always lead to that vehicle being overpriced, and impossible to work on. The two stroke is simplicity that make more power than a four stroke with half the displacement. Leave it to the 4 strokes to be computerized.
Harry Slother If you don't evolve the 2-stroke it will disappear (which it did for some time). Its not more complicated then an efi on a 4-stroke. I don't see any problem with the oil injection. It been around forever on snowmobiles. If jetting is sooo simple then why is everyone running way to rich? Sure, during summer and winter you are fine with one setting but during spring and autumn it's a pita. If we still want road legal 2-strokes this needs to happen.
pelleper road legal 2 strokes and motocross bikes are two different things. Oil injection on snowmobiles is a problem, they still can’t make a reliable way of doing it. Snowmobiles blow up all the time because of them. People take them because if it fails you don’t even know. There is nothing wrong with running rich. All two strokes run a little rich and they should. Would you rather run lean and blow up? I don’t have a problem with fuel injection two strokes but they should make a carb and inject model of every bike.
Harry Slother I live in a country that has a lot of snowmobiles and I can't say that it's a regular problem. Agree to disagree. Wait and see if a lot of 2018 will blow up or not. Running rich often means to rich because of laziness. I think that the TPIs are running way better then any carb I have ridden. Well, I ride enduro so I need it road legal. Can't speak of motocross but I don't see any problem with low tech (which tpi is) reducing fuel and oil burn. We are not talking about shitty tech like EGR and adblue.
it wont happen now its to late the amout of rnd to bring them back would make them go bankrupt before they can realease it becuase of the greenys complaining about smoke if there wasnt new emmision laws it would be viable and ktm wouldnt sell them the fuel injection system cause every one would sell there ktms and buy a new honda

Hawk Gamer the R&D for a 2 stroke would make HONDA one of the largest car manufacturers in the world go bankrupt? Don’t be dumb.
It already does, look at the snowmobile world. My fuel injected twin 800 has full snap, when and where ever you want it. The power band is always available there is never any lag or weak rpm ranges like the old carb sleds.
asambi69 An injected 2 stroke will make more power than a carb at any rpm. That’s the point of it, maximum efficiency with no weak ranges like carbs face. Better on gas, more power, bigger power band. There are no cons besides serviceability and repair cost.
I'm sorry but it's obvious you're sticking MX riders to XC. You aren't lugging or climbing or weaving between tight spots. Just carving turns, just like the MX vids. Work on that please.
Cold start on TPI bikes it is very different as they only get pure oil injected into the crank and it takes time for oil to get to the piston specially in cold climate areas (like here where summer is +5C to +10C) and when doing winter riding. There is many videos here of pistons of TPI show wear marks probably caused by lack of lubrication on the piston during cold start. KTM should maybe make another cold start oil injector to lubricate the piston when starting. ........
Bought a new 2018 carburated 250 and it was about 2k less considering the discount and no set up fees. Cant find a TPI here in CO for below MSRP without setup fees. Lectron carb made it run even better than the TPI and is more reliable.
Probably because the engine is at load and the sensor will squirt more oil than the carburetor counterpart but we all know most 2 strokes drivers who engine brake gives it continuous throttle blips who can resist those lol
I've engine breakes all my 2 strokes and have never had an engine blow up on me. Even had a chunk of the top of my piston break off and shoot out the exhaust and have my bike still run with a chunk missing from the piston. It ran like shit and wouldn't open up, but it didn't fuck up the barrel or anything, so I just needed a new piston and rings and I was good to go
I've ridden carb and tpi side by side. And I prefer the carb over the tpi just because how simple and robust they are. The tpi is really cool but it just feels like a 4 stroke to me. Id probably rather just buy a 350 4 stroke than the tpi.
ACreativeName ONLY THING THAT MATTERS, 10 TIME WORLD MOTORCROSS CHAMPIONS, DIRECT TO SHOWROOM FLOOR. HONDA KTM IS FOR OFFROAD TRAILS WHERE THE FLAGMAN AND TIME CLOCK DONT WORK. RETIREEEEEEE RIDING, THEY USE HANDICAP CANES ON MONDAY TO GALLOP KTM SHOWROOM. AND IM OOOOOOOOLD TOOOOOOOOO.
Honestly tpi seems like the future but a perfectly tuned and jetted carb bike isn’t worth selling and buying a tpi. Just not right now. I see problems in the computer that can go wrong and there goes your bike. Yikes, staying with carb until proven otherwise
AkaComeau fucking right my dude you know what your talking about. I'll take a perfect jetted bike over fuel injected any day. If you want a more complete combustion and torque on low end, use a hose running from your gas tank to inject gasoline vapour into your carburetor. Better Milage and more power
mcnameva my bike runs with an oil pump for 20 years and my uncles bike even longer. The oil sStem shouldn't be a problem same with the fuel injection. Athena uploaded a video of an injection system for 2s yeeeaars ago. This system is really good because the manufacturer can't do this when they know it can cause trouble.
Arved Ludwig no system is perfect. They all fail with time it's just the consequences for oil injection failure can be dramatic. I have seen it happen on sleds and I know it's similar with 2 stroke watercraft.
The problem with snowmobile and dirt bike 2 stroke fuel injection is that the main purpose of EFI is to satisfy the EPA goons, not to satisfy you the customer. Of course many enthusiasts will want one no matter what, but understand that you violate the laws of physics when you lean burn a 2 stroke and still expect long engine life. The result will be more frequent top end rebuilds due to inadequate lubrication unless you remap the fuel system to increase fuel supply and also increase oil pump output to match. Look at the newer snowmobiles where the factory recommended piston and ring replacement is around a 1000 miles. My carburetted sleds would go 5,000 to 8,000 miles or more before a top end job was needed. So when you purchase that new EFI 2 stroke dirt bike, enjoy it but be ready to accept the fact that more frequent engine refreshening will be part of your territory unless you just get a new bike every 6 months.
just yesterday i went for a ride, got my 2012 exc 250 jetted in a sunny afternoon a week ago, the ride started in the morning and it was cold, the bike didn't have torque down low, it was pretty bad, then after a cuople of hours temperature started to rise and the bike was running like it should.... efi is here to save us (can't really change needle/needle clip position/jets mid ride damnit)
Glitch, get the new map, already available here from KTM dealers makes a big difference glitch and lower sorted, yet to get a ride on this v my 17 250exc. Also really only weak points aim hearing is fuel pump and oil pump and quality of oil reservoir for the oil injection and filler to res! That said talking to some mechs about the reliability and already what they can see is less wear on top and bottom ends, because no fuel is mixed the bottom end is oil only so no fuel to corrode the bottom end, they reckon should get twice the service life out of a bottom end easily! Also the top end because of near perfect atomisation they reckon up to 200hrs on a top end, before all you carb bois get upset just think about those too facts alone and also what this will do re pipes silencers etc, aim a 2t man to the core and love the simplicity but this is imo a big deal, and also hearing the 250 may impact 300 sales here atleast where we have no restrictions off road, the bike pulls amazingly aim being told by 300 guys now saying what I been saying for years you only need a 250, ride one with the new map.
i heard jtm replaced all the faulty fuel tanks with stronger ones and if some one is going to bitch about a efi 2 stroke tell them that the only way you can keep carbs is if our bikes are the same from now on like the klr650 and then its not viable for ktm or husky to make them any more because of greenys
I'm really optimistic about this tech, really as just a means to allow for year-round riding of a 2 stroke. I live in CA, and so these bikes get what's called a "red sticker" which limits your riding season. I find w stroke bikes are lighter and tend to carry the weight of the motor lower in the chassis for better handling. I do like the simplicity of a 2 stroke (no valves) and the fuel injection does complicate things slightly, but I think I'm willing to trade it for year-round riding... now if these things weren't damn near almost $10K...
The only reason I switched to all efi is cuz they warm up way faster. Growing up going from crf80 to crf230 I always have had issues getting the bikes warmed up to ride and fucking with the chokes. Now having my crf250l and fz07 I just start them and by the time I get my gloves and helmet on they’re ready to go.
In Europa! GAS IS EXPENSIVE. I lived in Austria. So the TPI was engineered to WHAT???? A pair of Levi's cost over $100.00 USD's Mikuni with a JDJETTING on a 2-stroke in America on my 2019 KTM
Same weight difference if you would choose a linkage VS PDS (husky vs ktm). Also, you can carry less fuel and get the same range so I wouldn't call it a deal breaker.
Why do you guys ride like MX riders in the woods? I bet that lasted a whole 30 seconds of the time the camera was actually rolling. I did see you come close to a tree at the very beginning though. Lol.
How would the cylinder scavenge? The crankcase is used as an air pump to push air through the transfer ports. Unless you supercharge it like a 2 stroke diesel.....
U mean, the spring stiffens, or lets the shock have longer travel, with a bigger bump/jump/landing ?? No biggie, if I can't get it...So, is your bike a 380 2 stroke, cuz I've Never heard of a KTM 380...It's been a LOOOOOONG time, since I rode, but I'm planning on getting a 300 xc/xc w...
Gotcha ..Thanks 4 hanging in their w/ me !! I'm never gonna a hardcore track guy...That's a BEAST, being an already HUGE 2T, w/ that MUCH ADDED power...NICE :):) Take Care Reality Check 123 :):)
Can't wait till this is mainstream. Efi is more efficient, and can efi can atomize fuel better, increasing power and efficiency. Most don't know that the more you atomize fuel ,the more efficient at burning the gas will be at ingition. When this is mainstream for 2 strokes, them thumpers will be really running behind, not like thumpers have ever been faster anyhow. 4 strokes have to have 2x the cc displacement compared to 2 strokes to make same power out put. #2 strokes forever
the 2 stroke FI is the future. 2 stroke can only be applied on a single piston. and FI was designed for 4 stroke or multiple pistons. nobody knew or at least tested to make a 2 stoke FI until now. the cylinder head is eliminated, the air overlap in a two stroke is eliminated because the gas will be injected from the top of the cylinder meaning fuel efficiency to the max. the FI version when reb at lower speed will make a tattering sound (chung2) the reason for this is because the FI was designed to limit the rpm at a certain max rpm.
well sleds have had battery or batteryless efi for almost 2 decades.... multiple brands/ multiple CC.... seems ok I do prefer my 07 450r carbed to a newer crf efi ...less wires, electric s, shit to go wrong, and more power....and cheaper and lighter i
2 strokes don't need rerevolutionizing they possibly did it for emissions 2 strokes are what they are we love there simplicity of design and simpleness to work on there power delivery i don't want them to advance they are good enough how they are the power if they mellow it out to be a 4 stroke there will be no need it being a 2 stroke its just stupid
They were fuel injecting two strokes since the late 90s on jetskies. Although it was pretty shit lol the dirt bike manufactures just haven't really had a reason to put money into developing a system because carbed two strokes are just easy, cheap and work great.
Another head shaking moment,here we have two clowns riding bikes in circumstances so far removed from what they were designed to do it makes me doubt human survival past the end of the week.They were designed not for dribbling around the undergrowth but for flat out off road work(like Paris/Dakar or ISDT) Before you hang your name (and reputation) on RUclips stick with the old adage before opening mouth please check brain is in gear.
This I find hilarious, the environmentalists complain about a 2 stroke polluting the air but yet a wore out 2 stroke won’t run requires a 100 dollar rebuild to have a like new bike again. A wore out 4 stroke will still run yet will smoke bad and pollute 10 times more than the 2 stroke ever did in its whole running life and cost 5 times more to rebuild. Oh yeah not to for get how much more oil a 4 stoke needs to run and how many times it has to be changed. Lmfao. Let em think that one over.

Not rely, most engines lose power when converting to FI, atleast in the infancy.
Did you notice any other improvements with the TPI? Cold weather starting, plug fouling, can you flood it?
The less moving parts the better for me. I’ll stick to a carb and a simple kick starter
@Jason Wong No kidding.

How much is the milage difference between them? ?
It sounds like the injected model is more adaptable for mountain use. How so? Is it self adjusting? Can it go from sea level to Aspen elevations?
Yup.
For what I've heard. Doesn't need ajustments.

Or you can spend $25 in brass, save over $470 and have a better running bike... .than a lectron.
I love Bike two Strokes. Made helo for Brasil.✊🇧🇷
does TPI give the advantage of using engine braking without risking to blow the engine?
Thats a good question
I mean the Computer could calculate how much oil is needet
Probably because the engine is at load and the sensor will squirt more oil than the carburetor counterpart
but we all know most 2 strokes drivers who engine brake gives it continuous throttle blips
who can resist those lol
What do you mean?
can you engine break a two-stroke if it has an oil sprayer?
Antonio Simuncic why not? It actually would help...probably better compression and throttle response
I've engine breakes all my 2 strokes and have never had an engine blow up on me. Even had a chunk of the top of my piston break off and shoot out the exhaust and have my bike still run with a chunk missing from the piston.

Not really any point. There isn’t any real resistance.
The carbon brushes on my TPI high pressure fuel pump plugged up the in the tank filter. Very common. Must remove tank. Big expense.
I've ridden carb and tpi side by side. And I prefer the carb over the tpi just because how simple and robust they are. The tpi is really cool but it just feels like a 4 stroke to me. Id probably rather just buy a 350 4 stroke than the tpi.
Would the oil injection work on the carbureted model similar to the older systems eliminating the need for premix ?
yep, beta has oil injection on the standard rr250-300 models

So u dont have to mix gas with tpi??
GREASElover32 That is correct. Separate oil chamber. When the oil is full it will take roughly 2 tanks or more of gas before needing a re-fill.
No, KTM states up to 5+ tanks before refilling.
Why can't we have a 2 stroke engine with a closed off oil system like a 4 stroke and then inject the fuel directly into the combustion area?

the 2 stroke FI is the future. 2 stroke can only be applied on a single piston. and FI was designed for 4 stroke or multiple pistons. nobody knew or at least tested to make a 2 stoke FI until now. the cylinder head is eliminated, the air overlap in a two stroke is eliminated because the gas will be injected from the top of the cylinder meaning fuel efficiency to the max. the FI version when reb at lower speed will make a tattering sound (chung2) the reason for this is because the FI was designed to limit the rpm at a certain max rpm.
lectron carb will beat tpi fuel eco and also better power carb ftw
It just seems like it’s to expensive and a carb is still the better way to go.
well sleds have had battery or batteryless efi for almost 2 decades.... multiple brands/ multiple CC....
seems ok
I do prefer my 07 450r carbed to a newer crf efi ...less wires, electric s, shit to go wrong, and more power....and cheaper and lighter
i
carb.tpi ok for sumtine or maico700
Street legal? 2 strokes so light and easy maintenance
Good looking bikes!
PURE MUSIC!
Pros and cons noted give me the carb
2 strokes don't need rerevolutionizing they possibly did it for emissions 2 strokes are what they are we love there simplicity of design and simpleness to work on there power delivery i don't want them to advance they are good enough how they are the power if they mellow it out to be a 4 stroke there will be no need it being a 2 stroke its just stupid
Until you set the float and correctly jet the carb bike, you cant compare the two, can you?
Dont tell me the one jetting is alright. Its rich.
hold on peeps why aren't you all excited about having zero fuel charge bleed-through? Was that solved already?
Great test 😍🔝🔝
Just get a carb version and slap a Lectron carb on it and it's the best
Nice vid guys! Thanks
Does Mark Tilley talk with these awkward pauses in real life too?
Carb with lectron is probably better
watched the whole video in slowest motion lol watch it
That's not oil injection, that's just spraying oil into the crankcase...
I don't know how reliable those oil injectors are but if it fails it seems catastrophic. I think I would stick with carbureted.
You act as if oil injected 2 strokes dont exist for decades already
Carburator..for easy maintainance..
to much things that could go wrong
Its been around for years !!
mixalis what has
They were fuel injecting two strokes since the late 90s on jetskies. Although it was pretty shit lol the dirt bike manufactures just haven't really had a reason to put money into developing a system because carbed two strokes are just easy, cheap and work great.
Jalopy Rider well KTM has been working on there fuel injected two strokes for around 13 years! So yes they have taken a long time to develop it
Please Ktm bike price kya hai
whos here know the brand from germany that has a 720cc single cylinder 2troke engine?
I think it's a maico, because they have a 720 2-stroke.
Japan stopping all 2 stroke production. I'm done with Japan brands
Yz, yzx?
tbh only reason why honda kawi and suzki stopped making 2 stromes because none could compete with yz
I miss my cr250
Lectron is the future
Just buy a electron carb
First nice video
Nice ktm.
Carb > fuel injection
Fuel injection > carb. There, I fixed it for you.
Good bye 4 strokes
too noisy loud
I have a ktm 85 sx
Bet that fucker rips your arms off 😂
Why would you not take them to a MX track to see which one was faster? Lame video..
Fuck oil injection I like to mix my own gas
Global waming fools the end of great smelling 2 strokes ((
Another head shaking moment,here we have two clowns riding bikes in circumstances so far removed from what they were designed to do it makes me doubt human survival past the end of the week.They were designed not for dribbling around the undergrowth but for flat out off road work(like Paris/Dakar or ISDT) Before you hang your name (and reputation) on RUclips stick with the old adage before opening mouth please check brain is in gear.
This I find hilarious, the environmentalists complain about a 2 stroke polluting the air but yet a wore out 2 stroke won’t run requires a 100 dollar rebuild to have a like new bike again. A wore out 4 stroke will still run yet will smoke bad and pollute 10 times more than the 2 stroke ever did in its whole running life and cost 5 times more to rebuild. Oh yeah not to for get how much more oil a 4 stoke needs to run and how many times it has to be changed. Lmfao. Let em think that one over.
