Is a harley davidson seat bolt a special size?

Yes, most stock Harley seat bolts have a specific thread pitch (often 1/4"-28 or 5/16"-18, depending on the model and year) and length. Using a generic bolt from a hardware store can result in stripped threads.

What do I need to mount a solo seat on a hardtail?

For a sprung solo seat, you'll typically need a nose bracket or pivot, a pair of seat springs, and weld-on or bolt-on spring mounts that attach to your frame.

Do your hardware kits come with all the necessary pieces?

Absolutely. Our complete kits are designed for specific applications and include all the required bolts, nuts, washers, and bushings needed for a clean and proper installation.
