Hardware and More

If you’ve never left a bolt (or a part) on the highway behind you, you have likely never owned a vintage motorcycle. Engines these days can sound like scooters, whisper quiet, and hardly seem to shake below 5000 RPM. Such is the case with technology, it seems.

Vintage Japanese performance motorcycles are a different beast, though. It behooves us as custodians of these historic machines to make the rounds through our fasteners, torqueing every bolt and screw we can reach. Sooner or later, though, one’s going drop.

Odds are, there is a loose bolt on your vintage KZ1000 right now. These (and other) vintage Japanese performance bikes can really roar, but there is a downside to having all that muscle on tap. The rumble of that liter-sized engine translates to shaking throughout the motorcycle. Thanks to rubber mounts and dampers, we don’t feel as much of the shaking as we might otherwise, but it’s there, and it’s vibrating bolts losoe every time you ride.

Then, there’s the flipside. A vintage KZ barn find is a miraculous thing. Forty years ago, that motorcycle was the biggest thing in bikes, but someone left your new project out to rot. Forgotten, it sat in the corner of that barn for a generation. As mechanical ignition gave way to electronics, followed by fuel injection’s rise to dominance over carburetion, that Z1 sat patiently waiting for you to find her. Now, fly-by-wire and electronic rider aids are taking the skill out of riding, and you’re just beginning the process of restoring your KZ1000 to her original luster, or better.

If you get that bike down to the frame without stripping out bolts, consider yourself lucky. In all likelihood, you’ll be spraying cans worth of penetrating oil and snapping off a few studs on your way to a freshly powder coated frame.

Are you really even thinking about putting this classic performance motorcycle back together with the same, ancient bolts?

When you’re ready to begin rebuilding your vintage KZ1000, consider investing in all-new hardware. Z1 has prices set to beat your local big-box, home repair outlet. All of our bolts fit one vintage Japanese performance bike or another, so you won’t waste your time sifting through drawers and bins of bolts meant for hanging iron or hiding beneath the hoods of pick-up trucks.

Z1 stainless steel bolts will beautify your KZ, and you will not have oxidizing issues for years to come. For more utilitarian purposes, we have zinc-coated steel bolts that are the equal of any of your vintage KZ1000’s stock fasteners. From hex-head bolts to pan heads, nuts and washers, Z1 has everything you need to reassemble your vintage Japanese bike securely and professionally.
