For the 2018 250 sx model test you wrote "(2) Deprive the engine of air. For test riders who thought the engine was too aggressive, we put tape over the airbox vent on our KTM’s side panel. This strategy may sound strange, but it turns the KTM airbox into a Husqvarna airbox. The hit was made more manageable, and the powerband revved out further. All it takes is a strip of duct tape and one minute of your time." KTM did exactly what you recommended and now you're complaining about it and recommend drilling holes in the air box? Another surprising part of that test was your complaints about jetting. "In the KTM 250SX owner’s manual, it says to run a gas-to-oil ratio of 60:1. We thought it was a typo and ignored it. But, the more we struggled with the Mikuni jetting, the more the KTM factory mechanics asked us to switch from Maxima at 40:1 to Maxima at 60:1. Finally, we folded and put the stock jetting back in our bike and sent three test riders out on 40:1 fuel. Then, we switched the bikes to 60:1 and-voila!-the 60:1 ratio was better... The only jetting change we made was to go to a use the air screw to select a new pilot jet size." KTM has tuned their 250 two-strokes to run at 60:1 at least since the mid 2000's. You're supposed to be giving advice on jetting and haven't even checked the owner's manual for proper mix ratio on these bikes for over a decade? This really makes me question your opinions on bike tests which I've always highly regarded.
Haha, I love you bro. Dunno who these guys are testing but the narrator came even say huskVARna properly, dude called it HUSKAvarna...I mean, wth dude? These guys sold like whiney snots, must find something to complain about. My 03 SX250 had more power than the same year SX450F. Every year since then they've been trying to take what feels like essentially an overgrown 125 on steroids with a bad attitude. McGrath only out on a Pro Circuit pipe to race again full factory bikes. That's how insane the works replica 03 250SX is. I added a 6 oz Stealy flywheel, lower gearing and the PC pipe silencer combo. Holeshot city.
I never thought it was possible. A comment I read, that I agree 100% and can only hit like and say thanks. MXA should take note, and then throw you a job :)
Ive noticed these guys are so negative about bikes, here i am looking to buy a new bike and whether to stay 2 stroke or go 4 stroke and the reviews i watch make me want to find a good ole 2005 RM 250 LOL
Why buy a brand new bike and worry about the jetting, suspension etc??? Yz250 is perfectly dialed straight out of the box with the best suspension on the market and still cheaper. I guess that's why Yamaha doesn't change the YZ. They worry that they will make it worse 😂😂😂
Always good to see a two stroke still being produced. This makes happy that I have 2017 xc250 after hearing of the breathing problems they have now with newer bikes
TM, Yamaha, and Husqvarna still produce two strokes so there's not only one which I'm sold on Yamaha if only I had a yz 125. I currently have a 2018 kx 100 2t it's good but I need a bigger bike soon.
Thanks for the information on the 2019 KTM 250SX. I’ve gotten a lot of very valuable information from Motocross Action Magazine from 1992 till now. So thanks to all at Motocross Action.
I had one for a few months. The power was all mid. Signed off fast an hard. Suspension was stiff an was tough to feel confident on. Ended up trading it for a 450 husky. An i have a yz250 if i still want to rip a smoker. If your looking to get this bike. Just be prepared ro work out some kinks.
Tm period! Better everything and looks way better and has an electronic power valve and perfect suspension! I bought a tm300mx $2000 cheaper than that orange pos or husky 250 and it included suspension work, graphics, oils, hr meter, polished frame, and a knowledgeable dealer to spend the day at the track tuning it while I rode it. Best customer service ever and if I need a part it’s at my door step next day AST suspensions in Port St. Lucie florida
Some help please I am to buy about a Ltd 250 sx 2016 and ktm 125 sx 2018 ...what do you think is better?i want 250 but I have listen that after 2017 the ktm did some upgrades in the motor and in some other part that was very necessary ....so guys help me out do you know something about thouse upgrades and what should be best choice ? Both are in very good with no much hours just the 250 is a bit more expensive..heeelp😱
Since the YZ, is basically the same in the last 10 years, or so...Y do they say it's not that far off from the SX ?? KTM, is constantly improving at least a bit every year...Is the YZ that good ?
No - it is not as it is the same rehash and the KTM has invested money in 2 strokes. KTM will be TPI and Yamaha will drop the 125/250 like a rock due to no investment in TPI.
@@@mt1885 Alright...I agree, that makes a lot of sense, that Yamaha can't continue to go w/ the same ol', same ol' and expect to survive in that market...Thanks Aris :):)
@@davidgeerling9871 I would buy KTM since they spending money on 2stroke bikes. So I supports KTM since they keep making new changes and the TPI is the only way to saves them.
Buy the KTM, these guys are talking performance ONLY. The price difference is sure to the QUALITY. Your YZ will be willing in the way to wearing out when the KTM is just breaking in. Cadillac vs Chevy. Mercedes vs Nissan. Both are great, but one is clearly better. After sitting for 7 tears in a garage, my 03 KTM 250SX started in only THREE KICKS a couple months ago.... Shocking me and my buddy Gerard. 3 kicks, near Jap bikes need that many to start and my German bike started after SEVEN YEARS in a cold garage... Hahahaha, don't waste your money on anything else.
Dude the yz is by far more reliable than the KTM. Especially the legendary yz125 . Its proven. Ktm are awesome bikes i like them a lot. They fit my riding style But the can't much kayaba suspension and the jetting is also not so easy to figure out. Especially since they put mikuni carburetor. The used to have keihin like the Yamaha
60:1 gas to oil ratio is RICH not lean. 60 parts gas to 1 part oil. Drilling holes in the air box increases air thereby LEANING out the mixture. C'mon MXA editors, after all these years? Jody W, are you out there?
I bought a 2013 ktm cause motocross action said it was the best money could buy then in 2015 the yz got new plastic and all the sudden it was king shit b.s love my ktm the yz feels old school compared to it
I just bought this bike and idk how they are bitching so much about every little small change. Feels very similar to the 2017 and 2018 to me but slimmer.
For 2021 Yamaha needs to finally update their 2 stroke like and implement a hydraulic clutch and counterbalancer to reduce vibration and that bike would leave these two fools (KTM/Husky) in the dust.
Yamaha are effing cowards. I BLAME them for this 4 stroke BS. What they spent telling you is 2T scare you, keep you always on your toes. 4T feel lazy but your are moving MUCH faster than you feel. Anyone notice his many top Pro riders have been paralyzed some this new 4T craze...I don't think I need to say any more. I've watched them, the 4T, do off things when the riders least expect it, grab a bit of traction here or there where the rider expects the bike to dance over the terrain... Motocross IS A BALLET dance, 2T dance over the terrain, 4T try to stay GLUED to the ground, that's good for road racing, NOT motocross.
@@vetb882 i think honda did the first deal with california to finish the 2 stroke,but cant verify that.Its a shame the sport went back to 4 strokes like the 1960 s . amazing how history can repeat.
@@mxmtbees you are so right. I see a seeing coming back though, them having the 125 all star races is getting the crowds excited again.

Truuueeee😂😂😂
9k for a new bike with jetting issues. No thank you I'll stick with my YZ
@Taylor Anderson that's why i lean towards th YZ.
It's a proven choice.
Plus its more reliable and more fun
I love my YZ...
I’ll definitely stick with my YZ.
YZ250 for me
I’ve owned both and I think the power curve on the YZ is soo much better for motocross.
Always good to see a two stroke still being produced. This makes happy that I have 2017 xc250 after hearing of the breathing problems they have now with newer bikes

Wow, a non PC review. How refreshing.
I wish the big 4 still continued to make there 2 stroke line and development.
Just wish KTM would give up on WP suspension and go with Kayaba SS. Nothing better.
It's their own company they wouldn't just cancel it they make 10k$ suspensions lol
In the real world, after riding both, the ktm/husky is overall a rediculously better bike then the yz
I mean the yz is almost 20 years old. One would hope so.
And rediculously more expensive as well.
KTM - RACE READY - they will get TPI as well they are developing on 2 strokes !!!
Also I'm hoping the 2020 model has FI and fuel maps like the SXF models.
