On fresh-from-the dealer bikes steering stops are very limiting, hence turning radius is very large. It is on of the first things owners should adjust.
There is is a bolt on each side of lower triple clamp, preventing forks and triple clamps from hitting the frame or radiator when handlebars are moved all the way to the left or to the right. On new bikes, these bolts are sticking out too much.
It is very easy to adjust steering stops - just loose the nut, tighten the bolt and re-tighten the nut. Rotate the handlebars to make sure forks or triple clamps are not hitting the frame or radiator.
It is that easy. This should significantly reduce turning radius of the bike.
