I'd say this should only apply to guys/gals that have been riding for years and are moving up from something like an XR200 they've absolutely mastered. I rode 250 2-Stroke MX Bikes for years offroad. The learning curve was super steep for me because I was a pure novice in the dirt (I rode junk 70s bikes in fields and dirt roads for years but never hit the gnar with those bikes). I like you took my KX 250 right into the woods and rode it in pure MX form. But I would've had a much easier time if I had been on a KDX though. I bought into the whole "KDX has shit suspension" thing and bought the KX for just a couple hundred bucks more than the KDX. On thing EVERY MX bike will need is a spark arrestor silencer if you plan on riding it on public lands. The flywheel weight is nice because you won't stall the bike as much. Not having it will probably teach you how to use the clutch better though. I ride a KTM 300 now and I feel like it's the best bike ever. It's so much easier to ride, not really because of the power plant but because it has suspension that is designed for riding in the woods.
