KX 100 is a mini, the KX 125 is a full size bike.

the KX100 is the same bike as a KX85, with a slightly larger engine.

That 125 is quite a different animal than your 125 4 stroke. If money isn't that big of an issue get the 125 and take er' easy until you get the hang of things.

You could always look at left over models and save some money there also.

The KX100 is a good bike for your size but not for much longer. So 2 key factors are how fast you're growing and what class you plan to race in, since you said you plan to race. As was pointed out, the KX125 is a full sized 2 stroke bike and may have to race against 250F's, which would be tough on a 125 (if so, AMA amateur rules now allow that 125 to be punched out to a 153cc). The KX100 is only legal in the supermini class, which is designed for kids moving up from 85's to 125's, but who aren't quite ready for a full sized bike. So if your local series has a supermini class you're good, if not, you'd have to ride it in the 125 class.

Have you tried sitting on either of these to see how comfortable you are?
