Motorcycle batteries tend to lose life quickly, especially in cold weather. If you kept your battery trickle charged or hooked up to a tender, it's probably in good shape. Nonetheless, check the leads for corrosion, and make sure they're attached snugly.
If applicable, make sure your battery is topped off with distilled water, and if it's not completely charged don't ride until you're confident it will hold a charge and not leave you stranded.
