[0006] Preferably, a sealing gasket is installed at the top end of the mounting hole, and a sealing ring is fixed at the middle position of the bottom end of the sealing gasket.

[0007] Preferably, the bottom end of the sealing gasket is inserted into the interior of the sealing groove, and a sealed connection is formed between the sealing gasket and the sealing groove.

[0008] Preferably, the sealing pad and the sealing ring are both made of rubber.

[0009] Preferably, the reinforcement structure includes a fixing groove, a first reinforcement rib and a second reinforcement rib. The fixing groove is arranged inside the bottom end of the rear flat fork assembly. The first reinforcement rib is fixed inside the fixing groove, and the second reinforcement rib is arranged on one side of the first reinforcement rib.

[0010] Preferably, a plurality of the first reinforcing ribs and the second reinforcing ribs are provided, and the plurality of the first reinforcing ribs and the second reinforcing ribs are cross-distributed.

[0011] Preferably, a plurality of the first reinforcing ribs and the second reinforcing ribs are provided, and the first reinforcing ribs and the second reinforcing ribs are welded together to form an integrated structure.

[0012] The utility model provides a motorcycle rear fork assembly, which has the following advantages:

[0013] By using sealing gaskets, sealing rings and sealing grooves, the connection between the mounting hole and the fixing bolt can be sealed during installation, so that when the rear fork assembly is exposed to rain, the inside of the mounting hole will not rust, making it easier to remove the fixing bolt inside the mounting hole, thereby improving the waterproof effect.

[0014] By using the first reinforcing rib and the second reinforcing rib, the internal strength of the rear flat fork assembly can be enhanced, making the rear flat fork assembly stronger and less prone to bending during use, thereby improving the reinforcement work.
