I've got an EASIER solution than all of these. Don't use R1/R6, use Suzuki GSXR-600 Front end (get from wrecker like I did fo $600), and then go to www.cognitomoto.com and order their CNC'd front hub bolt on ready, just have it laced up at Buchannans in LA and start rolling. Allballs will have the bearings, and from what I hear (haven't actually installed yet), there is enough room in the triples to do it seamlessly!
