My dealer has this KX100 I've been looking at. It's a 2003 and looks brand new. pic below.

I'm thinking about trading my 01 mojave for it (which is in very nice shape)

I ride trails, tracks, fields, a little of everything. I weigh 145 and im 5'6" Should i go ahead and trade for it, or wait until i find a nice four-stroke for the riding i do?

 

if i was you i'd wait for a 125....they have more suspension, i'm your size (150 5'7") and can ride them no problems....learned how to ride bikes on a RM 250...to much of a powerband to start with let me tell you, and I test rode a KX100 and found it lacking excitment, then i rode a RM 125....decent power...good suspension and lots of fun

 

ya you will get board of the kx100 pritty quick but although i love them for the track, i think any two stroke has a bit of an agressive powerband for trail riding. If your going to be riding mostly trails i would go for somthing more along the lines of a kx250f, their sweet on the track but also make a good trails bike
