Fork Legs / Tubes

Fork Legs/Tubes are a part of suspension system. They are sliding tubes with long springs inside. They use hydraulic fluid for damping shock absorbers.

Characteristics of Fork Legs/Tubes

• Most two-wheelers have two fork legs/tubes: left fork leg and right fork leg.
• One or both fork legs carry a small cylinder inside the lower section which is basically an open-chamber shock absorber.
• A piston slides through the cartridge which is submerged in the fork oil.
• There is pressurized air inside the forks which can be adjusted through a valve in the top of the fork.
• 
  
• The motorcycle fork tubes are held together by a part called a triple clamp.

Functions of Fork Tubes/Legs

• The fork tubes hold the front wheel of a two-wheeler.
• Motorcycle fork tubes act as a shock absorber.

Materials used for making Fork Legs/Tubes
The two materials most commonly used for making fork legs/tubes are:

• Aluminum
• Steel

Maintenance of Fork Tubes/Legs

• Fork legs should always be adjusted equally for stability.
• The correct amount of recommended oil must be used. At the recommended period of time, the oil must be changed or the level checked.
