Not so sure it's "fixed", because the garage can be opened, but the quest isn't completed (and stay in journal without objective) and the bike don't appear in your list.Seems they fixed the exploit that you could pick up this at level 1 just by going there and open the garage using the keypad. Now you might actually need to do the associated quest to get it on a later part of the game.
You can ride the bike, but if you don't reload a save before openning the garage, I think the quest will always stay "bugged" in your journal and you can't aquire the bike
