This is correct. When you compress a gas pressurized shock, the shock shaft displaces volume inside the sealed portion of the shock body. The nitrogen inside the shock ends up being compressed to compensate for the decreased volume. It acutally has an increasing rate the more you compress the shock.. The Koni 30 series shocks I have on the FFR actually have a 'spring' rate of somewhere between 30 and 50 lb/in.

 

I like the huge hollow bar on mine. I wonder if it's lighter too?

 

It is. It's a half pound lighter than stock. (and 4.5 lbs lighter than the RB solid bar) It's "1.3 times stronger" than the solid bar, which is "2.3 times stronger" than the stock bar accoding to Racing Beat... So if the stock bar is a "1", the solid bar is a 3.3... and the hollow bar is a 7.6? Is that math right? Jeez.
