I'm 5'8" and 145 lbs. I'm 16 yrs. old and I'm looking for a two stroke bike to learn to ride on. I've never ridden a two stroke before just small four strokes, and I've heard they can be a handful if you aren't experienced.

I want a 2 stroke because I can find them used all over for cheap. I've been looking at a KX100. I don't really want to jump right on a 125 because I'm not that experienced, and an 85 would be a tad small. I'd take an 85 but I've heard the KX100 is good for trails and woods riding. And thats mainly what I'll be riding.

Plus, like I said, I don't have any experience on a 2 stroke and I've heard the KX100 had a broader powerband so I won't wreck it as easy while I'm still learning.

Should I get a KX100 or start out on some 85?

1) your physical size (both height and weight are important)
I'm 5'8" and 145 lbs. 16 yrs. old
2) How physical / aggressive are you ?
I'd say medium agressiveness
3) what do you plan to ride- MX/SX tracks, woods, fields with friends or ?????
In the woods, on trails, with friends. Just have some fun. Maybe an occasional MX track
4) Do you have any riding experience?
I've ridden bikes before but only a little. I've ridden my dad's playbike (Honda XR80) and my brother's Suzuki SP125. I still have room to learn a lot.
5) Do you think you will race ?
Probably not.
6) Are you mechanically inclined and will you be doing your own bike work?
My dad would do the mechanical work when needed.
7) Do YOU have a preferance to a brand/ motor choice (2 or 4 stroke)?
I want a 2 stroke because they are cheap when buying used. No brand preference really.
8) Do you have a dealer close by your home that you might use and what brand(s) does he carry?
I think there is a Honda/Yamaha dealer close and a Suzuki and Kawasaki dealer close.
9) How much do you plan to spend on a bike?
Anywhere up to about $2000.

Sorry I didn't put that in the first post. Thanks.

I think a good bike for you would be a 125 two stroke. It has a bit more power than an 80 or 100, and will allow you to advance to a bigger bike easier when you have the skill for it.

You can find them fairly cheap priced as well.

My 14 year old daughter has a KX100 and loves it. My son also rode it before that, until he got too tall (5'10"). For your height and intended use of the bike you should strongly consider a KDX; here's why:

A KX100 is a bigger KX85, I guess the same size as a Honda CR85 Expert. It has more torque and less peak HP than the KX85, though, making it a better woods bike (esp. with a 10oz flywheel weight). This means it has the same size wheels and about the same seat height as a TTR-125L or playbikes like that.

I'm 5'8" and ride it sometimes and it is a hoot, but I'm cramped on it so don't ride it too long. Of course the problem is the next bike up is a full size, whether that's a 125, 200, 250, etc. You could pick up a 125 pretty cheaply and add a flywheel weight, torque pipe, etc. to it. A better choice would be to get a KDX 200 or 220 since they can be had used in your price range, are much milder than the MX bikes, and are very reliable. Plus, if you get them used they'll often have some nice aftermarket goodies like new pipe, handguards, skid plate, etc.

If I went with a 125 two stroke and I put a flywheel weight on it and a torque pipe, would it be a decent trail bike? Or would the powerband still be pretty much off and on. The main reason I was looking at a KX100 was because I heard they had a broader powerband than an 85, and because it sat a little higher than an 85. I don't like the looks of the KDX because it weighs alot and another reason I want a two stroke is their light weight.

Again, I've never ridden a two stroke before, so i don't want to get a bike too powerful for me before I get more experience and confidence. Would a 125 kill me on the trails?

I'm about 5 foot 3, 120 pounds and I'm the perfect size for my KX100. I race harescrambles and motocross and it works extremely well for both. I've owned both a KX85 and the 100 and the 100 definetly has more power then the 85 (even dino readings say so), but I think you're a bit big for both of them. I'd definetly go for the 125. The KX125 has a really predictable powerband, and they're about 40 pounds less then the KDX200/220. As well, the bigger wheels of the 125 REALLY help in the trails. Flywheel weights are good, they will give the bike more torque, and make it a lot easier to control. Any 125 would do... I'd just pick whichever one you can find in decent shape that fits your budget :cool:

2 strokes for life said:
I third the KDX. Its not light but it makes nice smooth power easy to learn on and its easy to work on.
Yeah I read something about them having KIPS (Kawasaki Integrated Powervalve System) that allows the two stroke engine in the bike to make smooth power over a wide RPM range. Or something like that. That sounds cool because I was kind of cautious of getting a two stroke because I've heard an inexperienced rider hitting the powerband on a 2 stroke could cause you to eat dirt.

The only thing I don't like about the KDX is the weight. I wish there was someone around here who had one I could ride and try out.

Any relatively modern 2 stroke 125 will have a powervalve. Kawi just calls theirs KIPS. The big difference between the KDX and the 125 MX'ers is the porting, which is why the KDX's are so smooth and linear. The fact they're 200 or 220 cc also means they have more torque, which means they're harder to stall, another big benefit in the woods, when climbing hills, etc. The suspension is also softer sprung for woods riding compared to the 125 MX bikes, plus they have an 18" rear wheel (instead of 19"), spark arrestor, etc.

If you pick up a used KDX at a decent price you can ride it for a year and probably sell it for what you paid for it if you then decide you want more.

Cool man. The KDX sounds like a sweet bike. I really like the looks of a motocross bike, with the inverted forks in front and no headlights/taillights. But, I think I need to get over the looks and get what is practical. I think there is a KDX for sale on here anyway.

I'm liking the sound of the KDX more and more. It sounds like the perfect bike for me.

Here are some last questions I've got about the 200:

- Being a two stroke, but made for trails, can you lug around on them in low rpms and not worry about stalling or fouling a plug? Or do you have to keep them revved up in the high rpms like any other two stroke? How do the KDXs compare to riding a four stroke?

- How does the KDX200 compare to the XR250? Power wise.

the KDX can still foul, but thats where jetting comes in, its almost like the smoothness of a 4T with the available power of a 2T. i would imagine that the KDX is very close in power to the XR250, but im not sure.
