I have seen the RT180 fork swap but saw no details on what is entailed for proper disc and caliper alignment. Dip into XT & TTR parts bins for cables and hoses.
Forum member Gerry built my 35mm Tri-Z fork/ Banshee shock/ Raptor spring(?) set-up and I really, really like it.
I have complete TTR front end from 36mm forks, triples, cables, disc, hose, master cylinder to brake lever courtesy of CJ7Pilot to be mated with another Banshee shock/Raptor spring combo for Betty Boop. Supposedly finite element analysis by others indicates even with the 36mm bore the point of failure should be buckling of fork tubes before fracturing of the bored out cast triples.
