Yes, the tubular lowers are now available. Depending on when you order it is possible to have them in a few days or if someone has beat you to the punch it could take 2 weeks depending on orders and powder coating.
Here is a photo of a black powder coated arm shipping out 3/11/09 and the photo below it is a set sent uncoated to 3Dtim 3/10/09
One thing to remember is that these arms can be installed prior to the CBR rack/pinion conversion. They will greatly improve the handling of your stock steering and then you are set for down the road and the rack conversion.
