I have no idea what CBR you rode that you thought was extreme. But every road test review I've read always rank the CBR on top for street riding comfort (within the context of sportbikes). The R6 is extreme. Just look at where its clip ons are? They're below the triple clamp! The CBR is ABOVE the tripe clamp. The R6 also has a seat that slopes forward A LOT. The CBR's is much more level. In fact, ridden back to back, the CBR600rr's riding position is only one step less comfortable than the VFR800.
