Which dirt bike?

If you were buying a cheap dirt bike which one would you buy? I'm assuming something light, low maintenance and doesn't need servicing every two hours.

I use to ride a dirt bike (YT125) 20 years ago when growing up on the farm, but really haven't ridden one since. Anyway, have got the bug again so considering I'm a noob to this any suggestions?

Ta,

Cheapest of the cheap that's worth getting???

Serow.

Might be a bit of a challenge if you have to ride it anywhere to get to the green stuff though...you can do a RTW on one, but very slowly and not very comfortably.

Will go up anything without letting you down though, and fixable (apparently) with two sizes of hammer only.

If you want something a bit bigger and pokier, DRZ400....but it'll cost you twice what a Serow will.

Generally unbreakable though, leccy start and more than adequate off road
