Suspension & Swing Arm Question

[Joshua]

I was working on My bike this weekend and I noticed that I didn't like  the ..Uh Roll bar thing. Here is a picture to explain




Now I've seen alot of of pics without this on the bike. My question is if it is possible to just take it off wihout replace the major componets, I.E. the shock & swingarm, or is this justa difference between the older and newer bikes?

I don't know if it's still available, but Rizoma made a billet replacement.
