there is a kdx 200 for 2006 but i dont want to not be abile to ride it how much power does this bike really have.

how reliable are they.

how user friendly are they.

can i possibly hit the jumps that my friends hit with there 85's without bottoming out.

 

Get a KX 250 or a KDX 200

 

I have my kx125 about a month now and love the thing its my first bike also. I was considering a 250 but in the end I decided to stick with the 125 till I get used to it. Considering the pwoer of the 125 I would have killed my self off the 250. I'm 6foot1 and its a nice fit, i find it very comfortable. One thing is though you don't have much power til you get up in the revs (powervalve is great) but still it hauls my butt LOL! I hope to upgrade to a 250 next year, but the 125 is scary fast for a small motor I thought.

 

i'm 5'7 and 150 lbs....and a 250 2 stroker would be death on trails if your new to 2 wheels....if your trying to go fast they like to carry the front tire off the ground and bounce off rocks and roots...this makes for a very entertaining ride as you try to hang on to something that has a mind of it's own...i've ridden a 250, 125 and a KDX 220 and i think that the KDX would be the best begginer trail bike, they can handle jumps without bottoming and have lights and more space to put stuff (like a little bag on the rear fender/seat)

 

For what it's worth, the KDX200 sounds like it would be the best choice for you. You said that you like to ride rocky trails, not MX tracks, so a KX250 would be overkill. Plus, it will be your first bike. The 125s are fairly high-strung because they are designed for high RPM power. You don't want to be revving the crap out of a bike on a tight trail if you're a newbie. That only equals one thing: a crash. A 250 (two-stroke) would get you into a lot of trouble, and very quickly, too. They can get away from you in a hurry if you're not ready for the hit. I am 6' 6" and 225 pounds, and my last bike was a 2002 KX250. Even with my size and experience (~24 years), it would get away from me if I wasn't on top of it. You asked the about power of the KDX. It's roughly somewhere between the 125 and 250. It has more bottom-to-mid power than the 125 without being too revvy, but less than the 250 while being much mellower. Don't get the wrong idea. The KDX isn't a marshmallow with wheels. It is designed for trail use and the powerband has been tailored to follow suit. It is a very forgiving bike for a new rider. They are also reliable because Kawasaki has had years to make it into the bike that it is today. The KX100 shouldn't even be a choice for you. It's nothing more than a big-bore 85. You will be hunched-over when in a good riding position. The KDX is a full-sized bike, and therefore, has full-sized ergonomics, which will be much more comfortable on long rides. I don't think that I would jump a KDX too far or high because the suspension is much softer than an MX bike. Again, the reason is because it's designed for trails, not MX racing. That's not to say that you can't jump it, but don't try to emulate Seth Enslow. As far as the four-strokes go, I like them, but I wouldn't suggest one simply because of the fact that they are maintenance dependent. Two-strokes need upkeep too, but there a few other things to worry about with a four-stroke like engine oil, transmission oil, and valve adjustment. You will need to change the tranny oil more often on a thumper because they are a little harder on clutches. I know that the clutch plates are made of more durable materials in them, but I don't like to take chances, so I change the tranny oil more often on them to get any possible debris out of the system. Four-strokes don't really break down more or less than a two-stroke, but if you get behind on maintenance, they can be a nightmare, especially for an inexperienced rider. A two-stroke is a good bike to learn on because you learn to control the power and how to perform simple, routine maintenance. One you learn these two things, you can safely, and confidently, advance to a four-stroke if you want.
