Rules question: shooting with bikes

[nevermore]

Perhaps a stupid question, but I am confused with the rules for bikes: As on page 53 "each bike may fire one weapon for each rider", so the question is may the rider also fire a weapon?
For example: if you have a Space Marine bike (with twin-linked bolters) and a SM biker with a plasmagun can your fire both, the bolter AND the plasmagun?

No, the rule is that each rider may fire a weapon. The bike does not get to fire by itself.

So a space marine biker with a plasma gun may fire his twin-linked bolter, or his plasma gun, but not both. However, a space marine attack bike (which has two riders) armed with a twin-linked bolter and heavy bolter could fire both the twin-linked bolter and the heavy bolter. If the attack bike was equipped with a plasma gun, it could fire any two of the twin-linked bolter, plasma gun, and heavy bolter.

Thx.
I was afraid that it is not as glorious as I thought. Firing all weapons would be too sweet ...
