the 2020 KX motor is very similar to the CRF, if you see any dyno charts for both bikes you will notice they are almost identical....as you say both a bit soft off the bottom but rev like crazy.

I am pretty sure the new KX motor is almost the same as CRF bore and stroke wise. Bigger bore, less stroke = more top end power due to high rev limit. Literally just ride tracks in 2nd and 3rd and hold it WFO. On my 19 CRF, I shift into 4th so I don't have to bang off the limiter all the time, even though it sounds sweet.

Got to demo some 2020s today. Took out an rmz250 and 2 different kx250s one on the standard map and one on the aggressive map.

Im on an 18 rmz450 now. So the rmz250 i rode was pretty familiar. It was better in some ways then my 450 was stock. The 250s mapping was like spot on, ran super crisp. Engine was great. Chassis and suspension was definitly stiff. Landing jumps It was harsh and chop coming into corners was also harsh. Definitly could be helped big time with suspension work. Compared to the kx tho the rmz needed to be shifted more. It didnt rev out like the kx so the same jump i could overshoot in 3rd wide open on the kx the rmz needed 4th as it really stopped pulling in 3rd. Still tho the rmz was competitive and definitly pulled nice and ran great just not the top end like the kx.

The 2020 kx250s revved to the friggin moon tho! Holy crap they just rev and rev. The chassis and suspension honestly felt like it was set up for me. Like i must have been the target for that bike that's how it felt for me.

Engine was a little softer off bottom but it ripped up top and was easy to keep it revved and flow with it. I was so agressive on it and it was so easy to make it do whatever you wanted. Cut down early, or sweep wide, it was up for it. I really liked it.

So out of those 2 im sold on the kx as there's basically nothing id even want to touch on it, which is really saying something!!

Anyway wondering if anyone has some hours on them how are they holding up? With how much you have to rev them im wondering if i can get 50 hrs or so on a top end. Intermediate level moto.
