All depends, how much reserve capability the battery has is dependent upon its charge, how many times its been cycled, how much more load your putting on it. The list goes on.
After all the money you pay for one of these bikes, then all the mod's to it. Do you really want to leave it someplace with a dead battery? Or better yet have it leave you someplace with a dead battery?
I spent the money on a H-D 30amp OEM battery.
