I like the air forks. I got the 300sx. 47 hours on it now. Only issue was a false ceck engine light caused by accidentally hitting the start button while running. ECU flash fixed it. Always ran flawlessly and my bike was the first available in Arizona. So it was an early production model. Not sure why it seems like some bikes have issues. My friends new ktms have also been perfect.

Awsome review... me and my dad are looking at a new bike for me and we are debating about getting a ktm 125 or crf 150rb... you review has helped me so much 😊

what octane fuel do you use in it and where do you get it?

Spring forks are only for the off-road bikes in 24

how long to reach the engine

I have the same bike I just got to 20hrs with zero issues amazing bike

I'm riding MC250F and started looking for SX125s. What was the best thing you noticed when you stepped down to 125 ? Was it worth it ?

@FullThrottleEdits

I had always wanted a new 125, and the fuel injection was the main reason I bought it. It’s worth it, they’re so easy to ride with the fuel injection, it rides basically like a 4 stroke.

I have the same bike but i cant find no recalls for the 2023 ktm 125sx on the ktm website where are the recalls listed

Can it handle big guys? I am 6’3” and 230lbs. Years ago my Kawasaki would work well but it was in 1990 and it would burn clutches up and I was only 210 back then. I’m thinking these have 10 hp more so I would think the clutch assembly is stronger as well. I have 250’s and a 450 now but I want a bike with less power

I’m not sure how it would do with a bigger rider I weigh 160 so it’s hard to say but I will say I had a 2004 cr 125 and a 2002 kx 125 and both of those were way slower and way less powerful than this 23. So I would say give it a shot or look for a ktm 150sx. 40 hours on my stock clutch and if you watch my videos you can see I beat up my clutch so I think it’ll work.

What did you do to get rid of that bogging? I have a 2024 with 12 hours and it has that same issue, bogging when i brake tap, when im about to land and when i tap the clutch to shift. What did they do to fix this?

@FullThrottleEdits

20 күн бұрын

Make sure you’re up to date on all of the recalls, next run the vented side panel. The main issue with mine is that the squish gap on the base gasket was .05 off of what it needed to be making the piston detonate early and not reach the top of the cylinder, so after my first rebuild it ran amazingly.

should i get this bike if i want to start with riding?. I know the basics like shifting and stuff like that.

Yes, great bike to learn on especially with it being a fuel injected 2 stroke it’s really smooth and easy to handle.

can you turn off mapping and ride normal these newer bikes scare me but in the market for a ktm 125 unsure what year to go for

@FullThrottleEdits

Ай бұрын

You have to have mapping for fuel injected bikes, it’s a computer, it has to know how much fuel to send to the motor. These bikes run good now, you won’t have an issue with a 23+

I will be making a video on this soon after 55 hours and one rebuild but the secret to all the issues for me at least, was the squish gap is wrong from the factory, causing all the detonating issues. The bike has not skipped a beat since a top end was put it and I’ve never had an aftermarket tune or anything. Still loving the bike after the chaos when first buying.

the pure fact you count hours proofs these bikes are expensive garbage made to brake...... theres nothing worse than a bike that brakes on you on the middle of nowere in a montain...... buying and promoting this garbage just make manufacteurs take adavantage as they make most of the money from parts and maintenaince.

ehhh cant agree with that at all. you should look at it from a different point of view. Ktms previous gen was a great bike some of the best 2 strokes ever to come out. so now you're gonna fault them for being the only manufacture to continue to advance the two strokes when they are having problems with a whole new platform literally redesigned the whole entire bike... this happens to car manufacture all the time
