Good light adventure bike

I folks after some input, I currently own a Bmw Sertao. Its a great bike for on and off road, but I only way 60kg so its a bit of a lump to chuck about. Thinking of selling and getting something that is lighter, still with a good fuel size tank and fun on and off road. Bmw is worth about $7000 to $8000, so don't wish to spend more preferably less.

Thanks Leoagogo
