'91 CBR1000F RISERS

[JUSTPAT]

Hey everyone, I'm looking for risers which add add at least 3-4" of height to the existing clip ons.  This search is for my brother in Idaho who is computerless.  I seam to be only able to find 1 3/4" risers from gen mar.  My brother said someone told him that Renthal made 3" risers but when I looked online I couldn't find any (I do have an email in to them though).  Anybody here ever hear of these or is he SOL.  

Thanks for any replies.

Sorry for the late reply. As for 3-4", I think he's SOL. At that height, he would be looking at new thottle and choke cables, never mind the brake/clutch hoses

Spiegler has a conversion to round bars kit available. It uses the sportbike low bars that raise it 2"+ and back 5"+. If he needs to change out cables or use a different bar he could ask them what is needed.
