125s are THEE 2 stroke sound everyone loves. When I was young my absolute favorite part of a motocross was the 125 start. A swarm of 125s going for the holeshot sounds like a pissed off yellowjacket nest.

[@morley3810]

So for a guy like me, closer to 50 than 40, track rider for fun and general conditioning, the YZ 125 is still the best. Kind of like the YZ 250. The blue 2 strokes are still the bike that is truly best for MOST riders. They lose out on the really pointy end of the scale, but if people are really honest about how they ride most of the time, the Yamaha's are likely the best choice. It takes a bit of humility to acknowledge that for most guys lol.

[@danielnewman3441]

Great point. I'm 55 and have largely switched to hill climbs but still practice mx. I have a YZ125 and it's so much fun to ride. I'm at 225lbs so I had it bored to 144cc with an Athena. I'm a classic B rider and this bike is so much fun!

I'm having the exact same issues with my tc125 that they go into detail about at the 16:40 mark of the video. My boy came back to the pits mentioning of backfiring and slight hesitation up top. We then tried the green map and it cut out even worse and he was in a whoop section and almost ate it when it cut bad in the higher rpm. I'm glad a large platform such as this is bringing it to light and hopefully KTM can find a fix.

In my opinion, after buying a 2022 YZ 125. I was very comfortable on it. I’m 5 ft 7 ,160 lbs. I’m an intermediate rider, not a track racer although I go to the track. When I look at these numbers horsepower torque, I can’t help but think that if given the right pipe and silencer combo like the other European bikes have the YZ would fair roughly the same plus the suspension is so smooth and plush. It’s so confidence inspiring. So although it’s a little down on power from the other bikes, I think it would be close to top of the class with the mods. Beautiful bike and big smile fun factor too. Although to be honest a little bit tall for me and it had me thinking about the Husqvarna.

[@ryanxmx31]

Figured the gas gas would win ktm has some work to do with the tbi yet! Thanks mxa for the shootout

[@Kuhliifa]

I mean in the owners manual it does state to use “98 octane with a 2 stroke oil 1:40” so yeah the newer bikes would be at a disadvantage in this video and have some mapping issue like stated in the vid.

[@Dierk200185]

Yes thats a good point. The 2023 KTM 125 SX manual states" Super unleaded (ROZ 98 / RON 98 / PON 94) ( p. 139)" which is equvalent to ~93 US gas (R+M/2) if not even a tat higher. MXA states 2:28 they use 91 octane gas, therefore they run out of spec fuel. To conclude the KTM has detonation issues due to mapping should be revised imo @motocrossaction

[@abracing199]

thats 98 ron, not what we have in the US.

[@michael589m]

@@abracing199 U.S. 93 is equivalent to European (Ron) 98. The tbi system is not that intelligent, it doesn’t have O2 sensors and can’t make adjustments for an octane or oxygenated percentage change. It just mixes fuel and air. And then they add leaded fuel to bump the octane 🤦‍♂️ it’s just silly for them to go threw all this effort without using the proper fuel in these bikes. It’s comparable to doing a shootout without checking tire psi! It’s just silly.

[@eightzerotwo]

Yz is first in my book for 3 reasons. The price, suspension, and carburetor. I’m not sold on efi. Call me old school, but I like having the ability to swap jets vs. hooking a laptop to my bike or being forced to dump in C-12. Tech does not always trump mechanical in my book. Until there’s an app on my phone to adjust the mixture on the fly, efi is a deal breaker for me.

Yeah good point but the oil being pre mixed via the throttle body is super cool and a massive attraction to fuel injection.

But my point still stands, a little elbow grease and some plug readings and my bike is dialed.

I love it y'all but it's so annoying! When the 4 stroke started off, it was the yzf 400 and the 250 2 strokes smoked it! Then, the yzf 426, still not good enough! Then, the yzf 450 and thus the 450 class. Remember: Ricky Carmichael and James Stewart smoked all the 450s on 2 strokes but the 450s do have more torque and power... Here is what annoys me; When all manufacturers went to 450 (allowed to upgrade twice, 400, 426, 450) why didn't all 125s become 150s and all 250s become 300s? Could you imagine how much more fair that would be and it would be 1 upgrade, 125 to 150 and 250 to 300! Yz 300 2 stroke Yzf 450 4 stroke Kx 300 2 stroke Kxf 450 4 stroke Rm 300 2 stroke Rmz 450 4 stroke Cr 300 2 stroke Crf 450 4 stroke And so on with the 125s and 250f's That would have been awesome and I would have a kx 300 2 stroke instead of a Kx 250 2 stroke! Just saying fellow riders!
