How to Make a Motorcycle Backrest Mold

Traditionally, motorcycle backrests are provided with rigid arms that are supported by the frame of the motorcycle. They may also include a cushion that is mounted on a rigid post. They may be assembled into a pod that is secured to the saddle member of the motorcycle. When not in use, they can be folded down and removed. This allows the aerodynamics of the vehicle to be improved. They may also be used to secure packages.

A motorcycle backrest can be manufactured using a mold. The mold may be designed to incorporate the desired contours of the part. The assembly can be finished with a cover plate that is mounted over rivets to provide a finished appearance. The cover plate can be a synthetic resin or a material that is suited for the purpose.

The motorcycle backrest can be assembled with a molded foam cushion. A base plate is formed to accommodate the cushion. The base plate is formed to contain a large circular opening. The resin and reinforcing materials are cured simultaneously. The resin is a polyurethane or polyester. The reinforcing material is fibertech and creates a chemical bond between the foam and the base material.

The seatback structure is then removed from the mold. A second deposit of resin formulation is introduced into the cavity over the upper end of the frame member. The first deposit is partially cured. The resin and reinforcing material is cured along with the form cushioning material. A flexible cover is formed about the cushion layer. The cushion is then placed on the frame. The cover is then fastened to the frame with rivets.

The backrest can be inserted into the pod. The backrest is positioned at the forward end of the passenger seat portion. It can be secured in place by bolts or adhesives. In the event of an impact, the passenger portion should pivot forward to reduce the likelihood of injury. It can also be locked in position by a locking screw 54.

A tandem motorcycle saddle can be produced by integrating the backrest with the passenger seat portion. This allows the parts to be assembled in a consistent manner. It also allows for the hardware to be secured in the upholstery while the molding process is underway. The shaped seat can be shipped with the backrest assembled or unassembled.

A tandem motorcycle backrest with passenger handhold can provide comfort to the passenger while providing relative rigid support for the backrest. It can be securely installed and removed without harming the passenger. It can also be a safe configuration for the driver. It can also be a convenient way to secure cargo.

The backrest pod includes an outwardly extending flange. It is attached to the saddle member of the motorcycle and secured to the platform member. The backrest can be bolted to the saddle member, or the base plate can be adhesively engaged to the saddle member. The backrest can be pivoted to adjust the angle of the passenger seat.
