I've used a motorbike cover for some years - it works well most of the time, but there are a couple of issues that don't arise with a relatively heavy motorcycle parked on tarmac but will with a bike in a garden:
Look for a breathable fabric or vents (or both) because soil moisture and plant / grass respiration will cause condensation problems.
The cover will also act as a sail and the bike will blow over - the side stand isn't be stable enough - think about getting creative with locks to hold it upright.
Would something like a log store work? Make it part of the garden rather than a thing that lives in the garden?
