Sidecar frames

Types of Sidecar Frames

Sidecar frames are also known as sidecar chassis. They support the sidecar and connect it to the motorcycle, providing stability and safety. There are four main types of sidecar frames:

• Leading Link Frame

  This is the most common type of sidecar motorcycle frame. It has two arms that connect the front wheel hub to the sidecar body. One arm is longer than the other, creating a link. The arms act like shock absorbers, providing stability on rough terrain. Leading link sidecar frames are ideal for off-road riding.

• Earls Fork Frame

  This type of sidecar frame has a fork that resembles a bicycle's handlebars. The fork has two parallel arms that hold the front wheel hub and the motorcycle. The arms can pivot, allowing the front wheel to turn without affecting the sidecar. Earls fork frames are ideal for on-road riding.

• Swivel Joint Frame

  This type of sidecar frame has a swivel joint that connects the sidecar to the motorcycle. The joint allows the sidecar to move independently of the motorcycle. It reduces the impact of bumps and potholes on the rider. Swivel joint frames are ideal for high-speed riding.

• Solid Joint Frame

  This type of sidecar frame has a solid joint that connects the sidecar to the motorcycle. The joint transfers the bumps and potholes from the sidecar to the motorcycle. It is a simple and inexpensive sidecar frame. Solid joint frames are ideal for low-speed riding.
