Maybe the 65 mm is the travel if it's a suspension fork. How about a link to the brand and we could look up the specs from the MFR? 230 or 190 sound right for steerer tube lengths, but I'm at a loss why a new threadless fork would have more than one option of steerer tube length since the installer will nearly always cut the tube to length. I fear that the OP is looking at threaded forks.

65mm could be right for MTB rake, after all. I just looked at an SR suspension fork specified as a 255/130 in the Niagara Cycle catalog that had a 255 length steerer with 130 mm offset (rake) and selectable 100/80 mm of travel. Best look at the manufacturer page for the real information and not trust us internet pontificators.
