We have quite a few motorcycle storage customers in our 4′ units, so the answer is likely to be yes! They measure externally 8′ by 4′. However, you will need to allow for the door width because of the bike’s handlebars – this is approximately 2′ 6″. What we recommend is that you pop down and have a look. Although we are pretty full, we’ve almost always got an empty unit that you could wheel your bike up to and have a look at how comfortably it will fit. Any time that we’re open, there’s always someone here to talk through your storage needs and show you whatever container size you’d like to consider further. The great thing is that there’s more space lengthways than most bikes need, so you’ve got space to comfortably store additional items.
