rv6junkie said:I suggest that you try to ride 'em all before making your decision. I've owned KDX's and KX's. This past summer I decided it was time to get something different, so I rode a bunch of bikes. The YZ250F seemed about perfect for my needs. The WR250F is nice too, but the added weight turned me off.
While it is true that the new 250cc four-strokes require more maintenance, it's a very fair trade-off for the performance they offer and the confidence they inspire. I changed my airfilter and oil in my two-strokes often, so the added maintenance really isn't an issue for me. Further, I don’t live on the red-line, so engine longevity isn’t a concern to me. When the valves begin to move out of spec…it’s time for a top end – simple.
Fred T said:Now explain to him the cost of doing a 4T top end - also if he rides the bike the top ends need replacing every 25-35 hours. If not you can pay a huge price when it grenades. Not saying it not a good bike, it just requires dediecation.
rv6junkie said:Yes, all things being equal, I expect that a high-output four-stroke motor will cost more to own than a 2-stroke. How much more I don’t know. But as I stated in my earlier post, I’m willing to spend that difference because the performance that I can obtain out of the motor is worth it to me. I find the power delivery of a four-stoke more to my liking. Of course, that is my opinion; you obviously have a different view.

Fred T said:OK, now this guy asked:
I am 6'1" 210, do trail and track riding. I want something that will handle well in the woods, and also handle well at the track. I am considering a new KDX 200, EXC200, EXC300, YZF250, WR250, and KXF250 (reliable??). I would consider myself a little better than a beginer...but far from advanced! Any input on the subject would be great. I know posting this on the KDX forum is sure to bias the outcome! Thanks
You suggested the racing thumper, now it that becase you like it or because it would be a great fit for him? I only cautioned him because lots of people new to the "new generation" of high performance thumpers think of them like a Honda XR which they aren't. I just wanted him to be aware of this and even that the owners manuals suggest that they be rebuild every 25 hours. (Honda and KAW) You sound like you have this maint stuff down and are capable of checking valve clearances routinly and even are willing, ready and able to pull the top end and re do it. Maybe he isn't -maybe. But it don't hurt for him to have that information.
Fred T said:Those mini thumpers are a ball to ride I hear and many like them, just maybe it';s the perfect bike for him -I dunno. But I just wanted him to be aware it ain't no Honda XR either. Cool?
gargamel6 said:This morning I was convinced that I was going for a CRF250X. Then I came upon a great deal on a new 04 KDX220. I could do ALOT to it and still not be at the price of a KTM, or even the CRF. So once again I am back on the "green" side! The 250f's seem to require too much maintenance...maintenance I may or may not be able to do on my own. Seems it is more costly too to go down that road (repairs and price). I can't deny the affordability, and reliability of a KDX. I guess it just means I have to put some aftermarket crap on it right off the bat. At least it will be alot easier to find fun extras for a new KDX.
One question about the suspension...
Why is it KDX's don't have USD forks? What are the benefits of USD forks? Is it a good Idea to research putting USD forks on a KDX? maybe I'm superficial but I like the look of USD forks! Shock boots just remind me of XR's!
One last question about body parts...
Can I change the tank and seat to make it more like a KX (and almost all other bikes)? I like the idea of being able to get more "forward" on the tank. maybe tall seat foam is the ticket.
Thanks for all the input. It has helped (scare me away from 4 strokes!).

Tomck said:Fred T,
Most KDX owners seem to enjoy their bikes, but I was wondering if you could add a few more comments about your 2005 KTM 250 EXC. Do find that the 250 has good torque (e.g., for climbing hills) in the low to mid RPM range. Also, some folks mention vibration on KTM Talk. Has it been an issue for you? Thanks.
