Learn About Motorcycle Backrest Mold

Using a motorcycle backrest to provide support is an effective way to help a rider rest well. Backrests are typically designed to help redistribute the weight of a rider's body while at the same time minimizing impact aerodynamics. In addition to providing a stable surface to rest on, backrests can also be used to secure cargo. Depending on the design of the backrest, the backrest can be either a rigid frame or a pliable cover that is attached to the frame of the motorcycle. Backrests may also be used to enhance air circulation around the back of a rider.

Backrests are typically manufactured with a rigid frame member. This assembly typically includes a back support cushion and a support arm. The support arm is attached to the rigid frame and supports the backrest. This assembly is encapsulated in a rigid resin base. The back support cushion is molded over the frame, providing a cushion layer to support the backrest. The back support cushion has an oval-shaped design and measures about six-quarters of an inch in diameter. The back support cushion also has a large central aperture.

The backrest also features a handhold. This feature is typically located on the rear side of the backrest. This feature allows a passenger to hold onto the backrest while riding. The handhold is typically made of metal bars. The handhold may also be used for angle adjustment.

Aside from the handhold, the backrest also features an aperture. This feature is particularly useful for improving air circulation around the back of a rider. A cover plate is attached to the backrest to protect the backrest while in use and to provide a finished look. The cover plate is preferably made of a synthetic resin. This feature is also important in that it prevents the rivets used to attach the handhold to the backrest from slipping.

The backrest also features a small passenger seat. This feature is typically in the form of an upside-down teardrop shape. This feature is especially useful for the passenger. The small passenger seat has a corresponding cover which is attached to the backrest with back plate nuts. The cover's edges are also stretched to the rear side of the backrest. The cover's other notable feature is its ability to fold down.

The backrest also features a rigid frame member that has an arm extending outward from the mold cavity. This feature is a clever design because it allows the backrest to be reinstalled without taking the seat off the motorcycle. The backrest also features a pivot bolt that extends through the bore in the support arm. The pivot bolt allows the support arm to pivot on the frame of the motorcycle. The pivot bolt is accompanied by a nut that retains the bolt in place.

The backrest also features a foam cushion. This feature is also a clever design because it has a curved, symmetrical shape. The cushion is about six-quarters of an inch in height and has a corresponding peripheral portion that is dimensioned to hold the thumb of a passenger from the rear side.
