Yesterday TeamOrbit released their (beta) test demo of the RAT hoverbike for torque.
In this demo you'll be able to test out the hoverbike in one large map.
The hoverbike can be upgraded by going underneath stations, these will give you shield or speed upgrade for some time or permanent booster or weapon upgrades.
Different stations for different upgrades.
There are several 'rocket packs' on the hoverbike that fire of homing missles. These packs lock into an opponent and shoot the homing missles after the opponent.

There are some bugs in it but i can advice you to download it.
You can choose from a small demo release of 25mb or a larger one including a SDK (Software Development Kit) so you can start making your own maps.
There you can find 2 download locations for the small demo and 1 for the larger one.
