(this was supposed to be an edit from an earlier post, for some reason it duplicated here, I can edit this one, but not the previous one..... sorry, mostly the same but a few additional points)
I had a 2015 CRF250R and a 2018 CRF250R (plus a few other KTM's mixed in there.)
The bar bend on the XC does not feel natural to me, if I keep the bike I would try a different bend. Most of the XC is actually pretty good, but the WP suspension really spoils the party. The CRF bar bend feels perfect (to me). I am running 105 sag, the CRF feels slightly taller, but it only has one ride on it, the suspension will loosen up.
I feel the 2019 XC ergos are getting closer to "japanese feel" than they used to, but that bike still feels a bit long and low, slight chopper feel, the AER fork sits up a bit and has a LOT of stiction, not a great combo. It does not absorb trail trash like Showa or KYB does. The KTM pegs still have a slight rearward bias. (I am 6 ft 1 in. BTW...) I have never felt at home or comfortable on the KTM, my riding buddies all say I look like I am not riding with confidence and appear to be uncomfortable/fighting the bike. I do not enjoy riding that bike.....
The CRF egos fit me perfectly, I feel most comfortable on this bike, proper ergos put you in the correct position to ride/race aggressively, I feel relaxed, in control and instantly faster and more confident on the CRF, the suspension, handling and ergos are all helping that feeling. Showa suspension is plush, very little stiction and offers tremendous control. The power is strong smooth and very controllable = faster riding on tight trail. My riding buddies all agree I am flowing, comfortable/confident looking, and faster on the CRF by a good margin.
I have not ridden on a MX track with this bike yet. All single track so far. The way the bike corners and accelerates it will be really good on the track.
Gearing between the CRF250R and the RX is the same, but the radiators, FWW and stator are different on the R and RX (RX has a red plastic plug by left rad shroud for a headlight, JCR sells the plug and play headlight/wire/plug, they also sell a plug and play rad fan kit with a built in temp gauge). Mapping is also quite different, the mapping makes the feel of the engine and the feel of gearing very different, they really have a pronounced different feel between the 3 maps this year compared to last year. Nice change!
