For vehicles, they don't need any paper work apart from a copy of your RC, road tax, and insurance. They need the keys for the car - not the bike. In my case (Unicorn), they removed the mirrors, wrapped each of them and finally tied them to the seat. The seat was then wrapped, followed by covering the tank, the indicators, and the headlight. All wrapping was first with bubble wrap and then their soft cardboard. I didn't have any other accessories on the bike like tank cover or side box, so I am not sure what they do to those. Your bike is treated as part of your home luggage, and not a separate item as in the case of a car.
