Why do they push start the riders in motorcycle racing?

I'm talking about sportbike racing (Moto GP, Isle of Man).

They take off at the beginning of the race on their own but when they leave the pits they are pushed? I don't get it?

    When they start the race their engines are running.

    When leaving the pits the engines need to be started. Not many are pushed these days, most use a slave motor to start them.

    The bikes are lightweight racing machines so they do not have a starter mechanism.

    At the beginning of the TT race they have their engines already started by the pit crew, and they then set off at intervals.

    After a pit stop where the engine switched off the easiest way to restart the engine is with a bump or push start which you can Google.

    The rider has to do the bump start on his own but this expends energy so it is easier for his pit crew to give him a push to turn the engine over and get it restarted.
