I'm just curious, my friend claims his 2001 GasGas 321 shifted into reverse, is this possible?

I know some of the old trials bikes use to.

It can't mechanically shift into reverse. What can happen is the engine can run in reverse if the timing is set too aggressive. Two stroke motors don't know the direction they are running except for ignition timing. If the timing is close to TDC (top dead center) the engine will happily run backwards.
