Hi Ken,
I did give Alex a shout he did his years ago and it was fairly easy he try to get his 917 registered and it was a no go.
They asking for bumpers front and back, sun visors, can't have any lexan windows, brake warning lights for low brake fluid, and my head lights are to low to the ground center of light has to be 560 mm from grade, that one might not be do able with out serious mods and then all the typical stuff like horn seat belt etc...
