Motorcycle maintenance is more than doing maintenance on your motorcycle because you have to do it now or it is time to do it right away. Ongoing general maintenance will keep your motorcycle in great condition with little or no unpleasant surprises on the road. The humble battery is a very common cause for motorcycle breakdowns! Unfortunately they are awkward to get to and therefore do not get checked as often as they should. A battery only requires a little monthly maintenance to perform perfectly. Keep the battery charged to 100%, and recharge when the lights dim, the starter sounds weak, or the battery hasn't been used in more than two weeks. Use only distilled or deionized water, NOT tap water. Tap water has minerals in it that will not do the battery any good. Storage can be hard on batteries. In fact, non-use can leave them unable to hold a charge. It's easier than you think to buy the wrong battery for your vehicle. Unless your current battery is definitely the original equipment, you're taking a chance by not double checking before you purchase the new battery. So, when you go to a battery store to buy discount batteries, make sure the motorcycle battery is a good one.
