Hi Marten,
Obviously it depends on the actual weight of the particular RF4D you are interested in, but I was well within the aerobatic weight in both of my Fourniers when I weighed 85kg unclothed.
I am 184 cm high, and I fit in nicely, although I have moved the rudder pedals forwards by 5 cm and made my seats more reclined. Again that is with the standard canopy. Some RF4Ds have a lower canopy from a Ka13, so there is less headroom, so again it depends on the actual RF4D you want to fly.
I suggest you ask the owner of the next RF4D that you see.
Good luck, Bob
