Yes, you would be cramped on the XT225. My wife rides one (Write2ride) and she's only 5'3". I have a KLR250 and a DR650 and I'm 5'10". I am comfortable on both the KLR and DR, but feel cramped on the XT. The KLR is a bigger and taller frame compared to the XT. The seat height is also considerably taller. The only reason the KLR isn't my only bike is because of the kick start only. I have had my eye on a KLX250 for a while now, it seems to be the best of both worlds.
