Collection: Metric Bolts for Custom Motorcycles

Most motorcyclists notice the big components. The tank. The exhaust. The handlebars. The paintwork. Experienced bike builders, however, know that the quality of a well-built motorcycle is often revealed in the smallest details. And among these, bolts play a particularly important role. The right fasteners not only hold the motorcycle together but also contribute to its reliability, safety, and appearance. A carefully selected set of bolts can be just as much a part of a high-quality build as a premium air filter or a custom exhaust system. Metric standard bolts are used by most Japanese, European, and many modern custom motorcycles. Whether it's for maintenance, restoration, or building a completely unique project, the correct size and quality of bolts are essential for precise assembly. In this category, you will find metric bolts of various sizes, lengths, head designs, and surface treatments for custom, cruiser, café racer, scrambler, and other metric motorcycles. Because a characterful motorcycle isn't just special because of its striking components. But also because every single detail is in its place.
