Access garage 2nd attempt

So, I have the following problem. At the moment I still have a scooter that is smaller and more manageable than a boob. If I buy my Gixxer soon, I won’t get around the curve (see sketch attached). So far I always do it so that I go forward, beyond the “cross”, then back into the (somewhat provisional) garage. How far would you have to remove the flowerbed, that this technique also works on a big bike? Michi
