Long stroke D's (D16) have rubber built into the dampener.
I'll bet no one knew the Y5/Y7 pulley was 1.7 pounds lighter than the Y8/Z6 pulley. I know, I weighed them.

thats my stock pulley its damage but I did not use it on my b16, I used an unorthodox aluminum pulley, I also used to own a d16z6 it too has the same design with the rubber. I too used to think like you until I used one and destryed my motor, the motor is still good but needs new bearings.
fluidamper and ATI pulleys are design to help harmonics so it does not compare to aluminum pulleys, the NI pulley is design to be used with the type R so it don't compare to a chunk of aluminum.

Re: Lightened flywheel question...
well im not trying to claim im some expert on this ---- but i never had rubber in any of my d series pulleys or on my dohc zc currently. i want to look into getting a fluidamper but i don't think they made them for the d series. why don't early model d's have rubber dampening material?
