revo IQ is an updated version of the revolution, it has a more comfortable back of the head pad, but it has the same protection, Revo speed is kind of the same, but i think it is better, it has better sight lines for better vision, better, more comfortable padding, i don't know if they are lighter of heavier, but i do know that they look cooler than the revo IQ though, also the the revo speed is much newer so i am guessing that it is all around better, but it is your preference, go out to an athletic store and try them on, personally i thought that the revo speed is more comfortable and had better vision for inside the helmet
the revo speed helmet was invented in mid or late 2009
Revo is made with better keather

i don't know the exact weight of the helmet, but if you are looking for a comfortable protective helmet, the revo speed of this would be your helmet of choice, but if you are looking for the lighter of the two, take the revo speed
