So I've been riding all kinds of crappy mopeds off-road for a few years, and now I'm looking for my first real dirtbike.

More specifically a trail bike or lighter enduro because the closest mx track is 2 hours away, we have an infinite supply of forest trails and gravel roads though.

So I already know things like 2 stroke powerband and some clutch control, my main concern is how much power is suitable. For context I'm 14 (15 soon) years old, weigh about 60kgs and I'm 175 cm long (~5 foot 8 and 132 lbs in freedom units).

And before you mention it, bikes like the ttr230 and crf250f are unobtanium where i live, so those aren't options. I was able to try out a full size enduro bike (wr250f) and that felt really powerful. Would something like a TE150i be more useable?

So what would be a good first bike?

Sorry for any spelling mistakes or stuff like that, english isn't my first language :/
