Perhaps someone can enlighten me. But why do you need to use 41mm forks? Is it so they will slide directly into the SV's triple clamps?
Are the SV's stock geomytry dirt worthy?
Why not mod another dirtbikes triple clamps and forks to work on the SV frame? That's what I did with my Transalp-put some XR650R forks on her. Wasn't too hard.
