Most frames will be able to cope with 160kgs, it’s the wheels and some other components you might need to pick carefully.
Proper wheel build, with strong rims and DH casing tyres will help to prevent constant damage/pinch flats.
Any air fork on the market will struggle to get proper sag/height at your weight though. I’m 115kgs and have always had to run any air shocks and forks right at the stated upper limits to get results. That’s why I switched to coils as in most forks, I can find a spring to suit. But, I’m right at the upper end of spring weights as it is.
DH front disk brake with a big rotor will help with stopping too. Most other components should be good for your size as well.
