Hi Big Ted,
Moto marshalling involves many things, depending on the event. The event organisers will usually brief you on what you need to do. Basically we are there for rider safety/assistance. For this event the bike leads the riders with hazard lights going ( I have orange strobes )to warn other road users that a hazard is approaching, and to warn corner marshals that the bikes are on the way. You need to have your head on a swivel, and eyes all around your head, as some of the better riders will catch up to you unexpectedly especially on the down hill runs.
It helps to have a basic first aid knowledge, as the bike riders can do them selves a bit of damage when/if they crash. In this event not so much of an issue as you would be towards the front. Although we are volunteers, we do get some assistance with fuel costs, not sure what they are offering this year. If you register for the event, put OzSTOC in the Group .
Below is a video fro the UK that will give a bit of an idea..
