Hey all.
First time poster here, i thought i would share my experience & opinion of my last two bikes as i'm probably one of a handful who have had both and i wouldn't be surprised if my opinion is a little different to most. I'll try and keep it semi short. I've spent the last 17 years riding mx and have spent most of my life on two strokes.
In the last 6 years i've owned quite a few bikes, i generally own two at a time.
Starting with 14 YZ250F, 06 125SX, 08,YZ250, 17 250SX, 18 RMZ450, 19 250SXF (current bike).
I thought i would share my thoughts on the 17 250SX VS 19 250SXF.
Starting with the 17 250SX.
I bought this one at the start of 2018 and put 70 hours on it.
I won't get too much into the bike in stock form as there is a lot of information around which i believe is pretty spot on. It had a decent amount of mods on it for 60 hours so that's where my experience lies.
In stock form i found it fell flat on it's face at high rpms, had finicky jetting/fouling issues and i just couldn't get it to turn that well. Not taking away anything from the bike in stock form, i still found it to be superb, it just took a lot of modding along the way to get it to where i felt comfortable.
Mod wise i had a full pro circuit exhaust, v force 4 reeds, two stroke performance head/jetting spec, pwk 38 carb conversion, WP spring conversion and racetech gold valves front and rear.
This bike ran crisp and had plenty of smooth power from bottom to top. I could ride this in 2nd/3rd gear for most of the track, the power plant was still fairly aggressive but somewhat smoother/broader/stronger everywhere. I always had trouble finding rhythm on this bike, too hot/cold into and out of corners, too hot up to jumps, i could never just find any consistent rhythm on this bike, i would get 2-3 good perfect laps in a row and then just loose consistency.
Handling wise, i found it handled well but always had a natural cornering tendency to trace out wide arcs which naturally led me to take the outside lines. No issues sticking in an inside rut, just look a little effort to turn in.
Enter the 2019 250SXF.
I had just sold my 18 RMZ 450 which i had owned at the same time and found a cracker deal so i thought why not. I literally unbolted the forks, shocks, my favorite half bent bars and bent levers off the 250SX and bolted the right up to the SXF and took it to my local track.
All i can say is what a bike! Holy shit! This thing turns and pivots on a dime, not overly sure as to how as it is literally the exact same suspension/settings and frame geometry as the 250SX. I find that i can pick any section of the track, put it on the limiter, lean it over and go for it. The updated ergos are a welcome touch also, much slimmer and comfortable feeling.
Engine wise i find it has plenty of bottom/mid to cruise around the track in 3rd gear or shift between 2nd/3rd/4th and let it eat. I can't believe how far high it revs and how much power it puts out, but at the same time it's so smooth that you can hit the throttle early mid corner and launch out of it. It certainly takes a different no fear riding style to rev it till it sounds like it's going to shoot the piston out the top but i definitely don't agree with it being a 'top end motor only'.
The only change i've made is 2 up on the rear sprocket to help utilize 3rd gear a bit easier.
At the end of the day i seriously believe my new 250SXF is as fast or faster than my 250SX.

Handlingwise I think the engine brake helps your 250f to be better at turn in.
I guess at the end of the day it’s probably 50hp on the 2 stroke vs 40hp on the 4 stroke but I feel you can definitely put more power down for longer on the four stroke.
The Shop
DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Luxon 4-Post Bar Mounts
$189.95 - $239.95
And it’s the same power (especially since efi) everytime. You know exactly how much power the bike will make when you get on throttle. For me the predictability is the biggest advantage.
Now I care about having fun.
250cc two stroke in my future.
Try a 250f against a 250 2 stroke in the sand the difference bigger than you think...
You can make an argument for either because this sport is so dependant on rider and what suits one guy may not suit another
it was hard to get used too and it would fall on
it’s face on a steep up hill in the track once i rode it a while i got used to it and it handled better but felt heavier... for me it’s jsut the lack of low end grunt and the weight but the 4joke wasn’t as bad as i thought!
I put 100+ hours on the 250SX and 30 hours on each of the four-strokes.
I know that for how I ride and how much I ride, the 250F is where I need to be for the results I want. They are all awesome bikes, and each have their own strength. There is no one 'best bike' for everyone and the results are not hugely different for me, but are definitely more in favor of the four-stroke for me.
I just feel stoked that I get to choose and I get to ride/race these amazing bikes.
Pit Row
Both the ‘15 fc350 and ‘19 sxf350 i tried left me really impressed each time
Really nice amount of power without being overwhelming at times (imo) like a 450 can be
Seemed to thrive in the sand in places the 250f was lacking (again, in my opinion... im 225ibs so not exactly who the 250f is aimed at)
