Adding a solo seat to your motorcycle can make a huge difference in appearance and riding comfort, especially on a rigid framed bike. Here Kyle from Lowbrow Customs shows the installation of a solo seat step-by-step on his first Triumph build with a David Bird hardtail.
The first step in installing a solo seat is getting the necessary parts, which include a solo seat, front pivot or seat mount, a pair of springs, and spring mounts. Spring mounts can be fabricated or bought ready to weld on.
Mock up the seat and pivot and decide where it needs to be positioned for your height and riding position; the pictures shows a typical set up.
Mount your solo seat on the pivot. The slotted front pivot allows for adjustment of your seat position. Leather washers on the spring mounts keeps the springs from wearing away your paint, and also keeps the springs from squeeking.
Fender washers can be used to help hold the springs in place when you tighten down the nuts on the seat studs. Keep in mind that the springs compress when you sit on the seat, so make sure your seat is mounted level and not at a downward angle that will make you slide back when riding.
