Do you think i need a 64,17 inches feet (163 cm)?

If you are 82 kg and 182 cm, you are 180 lbs and a little under 6 feet tall.

In addition to the other boards mentioned here, consider the Prior Men's
Freeride (MFR). Prior also used to make a very highly-regarded
BX-specific board, if you contact Chris Prior I'm sure he could dust off
the molds and build one for you that exactly suits your requirements.
