Mr. Murphy says, if you have those spares, you'll never need them. Depending on the age of your bike, instead of letting the spares sit on the shelf, I'd install them. Of course, then you let yourself in for infant mortality, installation error (hey, no one's perfect), and the possibility that Suzuki will put out better-quality replacements in the near future, rendering your efforts moot. Unless you really need the bike to be operating day in and out, probably a waste of money and shelf space. And unless you've got a nice nitrogen-sparging set-up, and refrigerated storage space, the parts will age on your shelf, not quite as quickly as they'd age on your nice warm bike. So no telling if they'd be good if/when you needed them. I'd put the money into periodic battery replacement and a volt meter if you tend to load the electrical system heavily so as to minimize stress. For decades the aviation industry operated on the theory that parts fail from age, and some parts were replaced on that basis. They're finding that most failures occur immediately after installation (part faulty or installation error) or from wear (as opposed to age).
