That's exactly why I wanted to try the 150 for offroad. Although I am fast, for my level, on the 350 I would feel pretty whooped in the later stages of a race when its 100F outside. I raced the 150 the later half of the year in offroad and was getting ... more »

Leeham, you're right. Riding with my son a month ago coming up a jump, I decided to go for a double that none of the lower class was jumping while on my 350. Crashed and broke my hand

Hi All, Novice Vet Motocrosser and Vet Amateur Offroad racer here (57 and 150 lbs). I am wondering if anyone has personal experience comparing a KTM 150SX and any modern 250F. I currently have a 2016 350SXF that I am selling and had a 2018 450SXF that ... more »

Hi TxRider, North Texas rider here. Pondering a similar question. I started riding about 8 years ago (over 57 now) and went through a few bikes until I settled on a 2016 350 SXF. I was doing some MX racing in Vet classes and having fun. About 4 years ... more »

Bruce372, does that mean the stocker is better, Pro Circuit, FMF, or the stocker? I don't know that I am losing anything down low but when the trail opens up I will lose drive compared to the big bore thumpers.

I ended up putting he 150 kit on the bike. I was at the point where I needed a new piston and would also need to the cylinder reworked. So I just went for the 150 kit. The bike does pull harder. I may not be screaming the bike like the rest of you so ... more »

Thanks Ray. I will use this bike mostly for offroad racing in north Texas which has a few small hills and is mostly rocky. The rest can be fairly tight to flowing woods dumping out into a flat pasture. So it's hard to have a bike that fits all. I raced ... more »

Cool, thanks. Our races are sort of tight woods with a lot of more open, but they do like to throw in some rocky technical hill climbs. I've been able to do most of them but have troubles. Thought the 150 kit would help, not sure if I totally need it ... more »

CarilinoJo did you ever get to ride your bike? Interested in a report.

You're right Max. Doesn't make sense. The 350 can rev to the moon. Still just got stuck not having enough juice for MX. Not sure how to explain it (there is always another bike I will do better on!). I raced the 125 this weekend and had a blast through ... more »

I couldn't find a specific post speaking to a Rekluse on a KTM 125SX. I have a 2019 125SX that I am racing in Hare Scrambles type racing in north Texas. First race with it this weekend and had a blast in the tighter woods sections. Even did a little ... more »

Tracktor, is there data to show that the carb change does improve the power? Currently considering a Smart Carb. Of course the claims seem a little far fetched. 10% power improvement. They sent a dyno chart for a YZ125 and it did show that improvement. ... more »

Also, XC706, did you have to get new plastics when you put the XC tank on or did the SX ones fit?

XC706 can you speak to the Jarvis mods you did? I drilled the holes in the drain bolt. Have on order the jet block gasket kit. I didn't bother with the JD Jetting kit yet as I just found the jet block gasket issue. Wanted to try it and see how good it ... more »

Good info Joe, seems like the 150 is the best option. I've heard the 150 doesn't rev out like the 125 but in the woods may not matter. Nice looking bike.

Hi All, I have searched and can't find my specific answer. So don't kill me if it's in here. I have a 2019 KTM 125SX that I got a few months ago. Absolutely love this little bike, so light. Not too much power. Bought it for my son but he doesn't want ... more »

Hi Arrow, so how did it go? I have been racing cross country a few years on a 16 350sxf. Just got an 18 450sxf for MX. Bought my son a 19 125SX for MX. That is one fun bike. Makes me think about trying a 150XCW for cross country. What are your thoughts? ... more »
