You don't need the Wii Zapper for anything. It's just a gun shaped piece of plastic you stick your Wii Mote and Nunchuck into. I am thinking they will use it for control of the motor cycle. Put pressure on the left, you will turn left, and the other way too. They will leave control of the character to you, but I am thinking that they will let you lean with the balance board. Duck and jump with it. Although jumping might be a little over the top.
I completely understand why they would include the balance board in the game. This might push a lot of the Japanese into getting the game for it.
