With 34+dBi dishes (dual pol) and something like Netmetal/Netbox you should have a chance to get that kind of capacity with Mikrotik but it will depend on terrain profile, weather and spectrum usage on both sides.
There is no way to know until you actually put it in production.
If that is important link then I would split it in two shorter sections (50-60km max).
That way the link will have couple of ms bigger delay time but it will be more stable.
Either way there could be a lot of fine tuning until (and if) you get stable and satisfying result.
And, if that is really important link then I wouldn't do it with 802.11-standard-based-radio at all.
