Paddock stands

What are the advantages of a motorcycle paddock stand?
If you place your motorcycle on paddock stands, you can easily replace the wheels, lubricate the chain, polish rims and carry out other maintenance. A paddock stand is useful if you are standing in the paddock on the circuit and there is no motorcycle dealer nearby. Furthermore, you will not get any flat surfaces on your tires during winter storage when you lift them off the ground. Circuit bikes often do not have a stand, for this reason a paddock stand is even a must. At the front, the paddock stand is under your fork legs, there are holes in it. There is also a version that lifts the engine by the steering head.
