Hello,I have a GSXR400 1995,could someone tell me what mirrors fit from other bikes,having difficulty sourcing originals on the web.
Sorry about first post looking for help.

I bought a pair of pattern NC29/NC30 mirrors for my GK76 as they all have attachment studs set at 30 mm apart.
The CBR 400/VFR 400 mirror stalks are slightly longer with slightly bigger mirror heads so you'll have a better chance of seeing what's behind you! You'll have to shorten the threaded mounting studs for the GK76 mounting bolts though.
Or source a pair of suitable hex nuts.
