Just a couple of thoughts:
When you put your bike away in the autumn did you add any fuel stabiliser to the tank?
When you press the starter button does the engine turn over at normal speed or slowly & reluctantly?
If you can rule out degraded fuel- modern petrol doesnt last long unused-and your battery is in good condition then I would suspect spark plug LEADS & CAPS. Depending on the age of these thenyour sparksmay be tracking or earthing out rather than firing the cylinders.
Damp conditions in storage may aggravate this problem.
