Yamaha Motorcycle Nuts

Nuts

Improperly threaded nuts have a tendency to fall off when riding, leading to loose parts and, sometimes, an accident. Be sure your Yamaha restoration is authentic and safe with our 100-percent accurate Yamaha XS nuts. When it comes to hard to find parts. We've got them. We stock items like the auto advance retainer nut, the side-stand bolt with castle nut, front wheel axle nut, steering head lock nut and more. Mikes XS is also a great source for chrome acorn nuts; we have all the sizes you’ll need for your chopper, or any other XS build.
